Is CuLator a good choice for issues with blonde hair turning green?

YES!  CuLator is the perfect choice because it pulls copper out of the swimming pool water and the copper is what causes blonde hair to go green.  We recommend using a CuLator Ultra 4.0 when children, or anyone has hair turning green after swimming.  We have even had people call to say their very light skinned children have turned a bluish color.  Yep, that’s copper!  If you have gray hair your hair can turn bluish, as well.  That’s copper!

  Hair Turned Green from Swimming

When blonde hair turns green it is a sign that there is copper in the water.  Sequestering agents don’t get the copper out of the water, but CuLator does.

Here is what a used CuLator looks like with copper inside the CuLator Ultra 4.0.

Use CuLator Ultra 4.0 to Remove 0.4 Copper from 31,000 Gallons

CuLator Ultra 4.0
I have 0.4 copper in my pool currently. I am treating my pool for almost 3K ppb phosphate now. I used a sequestering agent a few weeks ago (Bioguard/SparkleUp) and then cleaned the filter with no reduction in copper. Do I need to add another sequestering agent to the water when I add the culator 4.0 in? My pool is about 31K gallons. Thanks for any advice!



Hi DC,

Thanks for the questions.  The sequestering agent will last about a month.  Just place the CuLator Ultra 4.0 into the pump basket and leave it in all summer.  You should be good to go!



CuLator Bag Leaking Question

 Question:  I purchased CuLator Ultra 4.0 and it’s been in my pool for 1 week.  It is starting to leak and very puffy. Is this normal?
Should I remove it from the skimmer already?
It is bluish green in color. Please see picture.  P.T.

CuLator Ultra Used With Copper Bound   CuLator Color Chart


That is perfectly normal!  And the color means it is pulling out copper and possibly some iron out of your pool water.  Often, in the manufacturing process, some of the polymers get onto the outside of the bag.  It will look like it is leaking, but it isn’t (unless there is a tear in the bag).

So, I would inspect the bag for rips and if there is nothing, then don’t worry about the product because it is working perfectly.  By the way, if the gel substance comes off the bag, it will get caught on the filter and keep working until you rinse the filter off.  And, the product is non-toxic.

If you are concerned, just take the CuLator out and rinse it in fresh water and place it back into your skimmer.


Frequently Asked Questions 2018

Here are some frequently asked questions (with our answers):

  • What exactly is CuLator Metal Eliminator?  CuLator is a patented non-toxic polymer which binds ionized metals out water and does not release it back into the water.  CuLator is manufactured in the USA in Fort Lauderdale.  CuLator products are 100% patented polymer.


  • What is the 4.0 Power Pack?  CuLator Ultra 4.0 is exactly the same as the PowerPak 1.0 BUT it has 4 times the amount of polymer, lasts a lot longer, and comes with a protective GatorEgg which allows it to be placed in the PUMP basket.  The 1.0 can ONLY be placed into the SKIMMER basket.  The 4.0 is great for people on well water, large pools, startups, filling after resurfacing, problem pools, heater blow outs, and people who don’t want to place anything into the skimmer basket.  Most people start with a 1.0 and then move to the 4.0.  Also, the 4.0 can be used in professional pools and you can string them together for very large pools and securely place them into a surge tank.  The 4.0 saves money and is a great product for the entire summer season.  It usually lasts 4-6 months depending on the quality of the pool water.


  • What’s the difference?  The PowerPak 1.0 is mainly used for smaller pools or people who are just starting to have some staining or water discoloration.  If the problem is larger or the metal levels are higher, then they should use the 4.0.  The main difference is the amount of CuLator polymer and the Ultra 4.0 has the protective GatorEgg which allows placement into the pump basket.
  • How does it work?  CuLator works because the polymers have a negative charge on them and “claws” that act like a sequestering agent and GRAB positively charged metals out of the pool water.  CuLator does not dissolve in water.  Once metals are removed or ELIMINATED from the water, they will not be release back into the water.  So, CuLator is a chelator which binds stain-causing metals out of water for removal and elimination.


  • How does one little pouch help 20K gallons of pool water?  Metal ions in the pool water are very attracted to the patented CuLator polymers inside the pouch.  The attraction is like a magnet and works at lightning speed.  The binding action is a chemical bond and is difficult to break.  Because the CuLator polymers have a very high binding capacity, it doesn’t take much to treat a big body of water.  This is great for reducing waste, shipping, and plastic bottles and helps protect the pool surface and the environment.


  • What are some benefits/advantages in using CuLator over other products (ie: Natural Chemistry’s Stain Free or ITS Stain Away – Metal Sequestering)?  Metal sequestering agents are temporary solutions while CuLator is a more permanent one. When you pour a sequestering agent into the water, it lasts about 3 weeks and is broken down by chlorine, sun, and time.  The sequestering agent doesn’t really REMOVE the metals, but rather holds them in solution temporarily until they break down and release the metal ions again (unless you are using CuLator).  If the sequestering agent is made with phosphonic acid, it breaks down into…phosphate!  So, you don’t want to use a phosphonic acid based sequestering agent.  CuLator is 100% polymer and NO PHOSPHATES.   With all that said, sequestering agents work great for temporary solutions, like when you are filling with well water, or at start-up.  For people on well water, we recommend a regular dose of sequestering agent (non-phosphate based) and a CuLator Ultra 4.0.  That combo seems to work great for most people.  CuLator, if used regularly, allows someone to reduce the over-use of sequestering agents and all those problems with TDS and phosphates that come with them.  Plus, CuLator is non-toxic and doesn’t dissolve in the water, so you aren’t swimming in it like you are a sequestering agent.


  • How do I determine if CuLator is the right product for me?  If you have ANY metals, then CuLator is right for your swimming pool.  If you are using a sequestering agent, then you should a CuLator.  If you are on well water or have a heater blow out then you need CuLator.  If you are using a copper algaecide you should treat with CuLator after.  If you have faux stone features, travertine (or any real stone) or bricks around the pool, you need CuLator.  If you have plantings or grass near the pool, then CuLator is a must.  If you have a salt generator or a salt system, use CuLator.  Salt water systems are very bad for staining because ALL salt has some iron mined with it.  If you look at the salt, there is always a yellowish tinge…that is iron and a lot gets into the pool.  Look at the bag…99% salt 1 % other.  So, if you dump 100 lbs of salt into your pool water…you can get up to a pound of other things including iron!  Usually, that is enough to stain a pool.  The other issue with salt pools is the pH always creeps up.  When the pH gets above 7.4-7.6, then there is a much great chance of staining.  CuLator helps prevent metal staining in all types of pools even if the pH goes up too high. Metal staining begins at .3 ppm…yep!  So, if you have anything above a .2,  use CuLator.  However, to PREVENT staining from occurring, I  recommend a 4.0 to EVERY pool owner every season as an insurance– just in case.  Metals come from everywhere (above), so why bother with staining if you can really prevent it with CuLator!


  • Does the pool operator have to do anything else before/after they use CuLator?  Not really!  CuLator works in all types of water and in a wide range of pH.  The operator only has to place the CuLator in the skimmer (1.0) or the pump basket (4.0) and make sure the pump is on for at least an hour to hydrate the polymers.  After that, they just have to check the bag once a week, or so, to make sure everything is good and to see if there is any color change inside the bag (that means the metals are trapped inside).


  • How long does CuLator last?  The PowerPak 1.0 lasts for a month or longer depending on how much metal is in the water.  Let’s say you have .5 iron in the water and the CuLator pulls that all out…you still have .5 capacity left.  So, the 1.0 could last another month or two depending on if there was more iron getting into the pool.  There is no way to test if the CuLator is done other than doing a total metal test to see if the levels are increasing.  The Ultra 4.0 can last for an entire summer season.  Just think of the 1.0=1 month and the 4.0=4 months.  Many people just get a new 1.0 and keep the old one in the skimmer until they are sure the old one is done working.  If the bag tears or breaks, no worries, the polymers are non-toxic and will get stuck on the filter media and keep working until they backwash or rinse.  The 4.0 often expands to fill the GatorEgg completely.  A good rule of thumb is when the 4.0 shrinks to half its expanded size, or when it feels squishy or sandy inside the bag, then it is time to replace.


  • Are there chemicals or situations that would affect the performance of CuLator?  Sort of… if you use lanthanides (phosphate removers), the CuLator will bind them out of the water; so, it can diminish the working capacity of both products , but only by a small amount.  However, the liquid would have to be poured directly onto the CuLator, which is not easy to do.  If you are using an algaecide, then I would take the CuLator out for a few days and then place it back into the pool water after the treatment is complete and the CuLator will pick up all the used up copper and prevent staining.  CuLator can be used, dried out and reused.  When dried, the polymers will turn hard like plastic, but will re-hydrate and continue to work as soon as they hit the water.  Also, if the pH goes below 7 (the bags are a double layer of a special cotton) the low acidic pH will begin to slowly eat away at the bag.  If you place the CuLator bag directly in a chlorine tab, the CuLator will still work fine, but the bag will be weakened by the tab (think bleach on a T-shirt).  Usually, if the CuLator is on a tab, it will last at least three months before starting to show signs of weakness.  It is best not to place them on a tab, but then again, the tab should be in a floater…not in the skimmer.

Periodic Products Introduces CuLator InLine Pro

We have been working hard at Periodic Products to manufacture a filter with CuLator Metal Eliminator inside…and we have done it!  After years of research, we have manufactured a pleated filter with the power of CuLator!  Plumbed into the swimming pool circulation system with 3/4″ connections, the CuLator InLine Pro allows a replaceable CuLator Filter to remove and eliminate up to 8 ppm dissolved metals from 20,000 gallons.  This new pleated filter system is an improvement over traditional CuLator products because of the added surface area which allows the CuLator polymers to grab more metals like iron, copper, manganese, and lead from your pool and spa water faster.  Don’t forget, that once the metals are bound to the CuLator, they are not coming off!  So, you don’t have to worry about metals dropping back into the water like sequestering agents and other products.

Iron Bacteria Eliminator Kit Worked!

Before and After Iron Bacteria Eliminator Kit

Before and After Iron Bacteria Eliminator Kit

Many thanks to Chris Walkerow at Periodic Products and Fred Schweer at Pool Rx for incredible help with our pool.

We’ve been dealing with gray/brown discoloration on the bottom of this pool in southwestern Pennsylvania for several years without success. Finally last fall, I reached out to Pool Rx whose sanitizing product we use. Fred worked with us and directed us toward C U Lator to deal with copper removal. In talking with Chris about the issue, he recommended that we use their Iron Bacteria Eliminator product to address the discoloration. So after dumping and refilling the pool to get rid of the very high chlorine stabilizer that had built up from past efforts, we followed Chris and Fred’s guidance to the letter. Nothing went in the pool this season without their approval. We couldn’t get the C U Lator products locally so we had them shipped up from Chris in Florida. Even liquid chlorine was very difficult to source locally: “Nobody uses that, use tablets or granular” is what we kept hearing. But we insisted on what these two chemists recommended.

We dumped and refilled the pool in late June, and completed the Iron Bacteria treatment just in time to swim over the July 4th weekend. The pool has been clear, clean, and stable the rest of the season! This is the first time in at least 3 years that we have had stable pool chemistry and had a normal pool bottom appearance. Our local pool supplier ran our water tests but quickly learned not to make any recommendations because we were “using another lab.” After about six weeks of consistently stable test results, they started to ask: “What are you putting in this pool?”

We HIGHLY recommend Chris and Fred for their outstanding ability to deal with pool chemistry issues. Apparently, a combination of iron bacteria in our fill water combined with clay soil, a high water table, and direct sunlight resulted in this persistent discoloration. Chris was the first to figure out a solution.

Attached are before and after pictures. A HUGE thank you to Chris and Fred!!!

Kids Hair Turned Green From Pool Water

Here is a recent question we received that I wanted to share:

I have a question regarding the Metal Eliminator. We have copper in our pool (about 2.0) no staining or water changing color… just the kids hair is getting a green tint. Do we have to use the Metal Sequester first (I did use metal free at the beginning of the season)? Or can I just get the CuLator Metal Eliminator and put it in my pump basket. Much Appreciated!!

K.D. California

Here is the response:


Copper will definitely turn your kids hair green.  No, you don’t have to use the Metal Sequester first, but rather use it at the same time with the CuLator Metal Eliminator Ultra 4.0 ( in your pump basket) for best results.  All metal sequestering agents have a limited life span.  Usually about three to four weeks; so, the best way to deal with stain-causing metals is to get them out of the water.  CuLator is the only product that gets the metal out of the swimming pool water.


Is Bonding Pool Water Important? YES!

Many pool owners do not understand the difference between grounding equipment versus bonding pool water.

Grounding Equipment:  Electrical wiring system which is a conductor that provides a low impedance path to the earth to prevent hazardous voltages from appearing on equipment.  All your pool equipment should be grounded for safety.

Bonding Pool Water:  Bonding ensures the safety of all pool swimmers by making sure there is no build up of electricity in the swimming pool water.  No current flow can take place between two bonded bodies because they have the same potential.  Bonding keeps people and electricity separated.

Bonding protects people and equipment by reducing current flow between pieces of equipment (or water, or swimmers) at different potentials.  The main reason for bonding swimming pool water is personnel safety.  Bonding prevents someone touching two pieces of equipment (including water) at the same time from receiving a shock (or worse) by becoming the path of equalization if they happen to be at different potentials

2008 the National Electrical Code (NEC) has mandated that pool water shall be electrically bonded, not just metals in the structure of the pool itself. NEC bonding requirements apply to in ground and above ground pools, and includes all metal components, equipment and the water itself. Correct pool bonding protects people, pets and pool equipment by reducing current flow between items of different potential.

All pool water should be bonded. Your pool water must be bonded when you do not have any metal touching the water (ladder, hand rail, metal fixture or light).  If you do not have bonded water, or you are unsure, a simple pool water bonding kit will do the trick.  Just make sure your bonding kit is stainless steel (do not use copper or other metals) like this one: Burndy Waterbug Pool Water Bonding Kit .

Here is a great article on swimming pool water bonding:

Jack’s Magic Stain ID Kit and Periodic Products No-Drain Metal Stain Eliminator Kit

Pool Stain Eliminator Kits

Here is a question we were asked by Glenn in Orlando:

In the past, I used “Jack’s” stain test kit. With that kit, I needed to use their “O2 Safe Shock” in addition to the copper stain remover, in order to get a reaction.
Will your stain remover kit work for copper without this added product?

Good question!  If you have a fresh stain, our No-Drain Metal Stain Eliminator Kit will work on removing the iron and copper stains and eliminating the metals from your pool water.  If you have had a stain for a long time, your stain may be calcified over and then you need to do a treatment like the Jack’s Magic “O2 Safe Shock” to remove the calcium layer and THEN do the stain treatment.

Don’t forget that when doing our stain treatment, you don’t have to do a stain test kit first because we have both types of stain treatments to remove iron stains and copper stains from your swimming pool surface.

The most important part of doing a stain treatment is to remember there are three parts:

  1. Treat and remove the metal stain
  2. Sequester the metals in the water
  3. Eliminate the metals with CuLator Metal Eliminator
