Beautiful Children in Swimming Pool

  1. In The Swim Super Stain Away: Suitable for various pool surfaces, this powerful agent eliminates stains caused by iron, copper, and manganese, enhancing water aesthetics. 


In this list, the term “Metal Remover” is a misnomer. Sequestering agents and chelating agents react with metal ions to produce molecules too small to be removed by pool filters. Metal removers sold in the pool industry do not remove metals from pool and spa water but rather suspend the metals in the water temporarily. The only product that REMOVES and ELIMINATES metals is CuLator Metal Remover and Stain Preventer. 

Maintaining a clean and balanced swimming pool is crucial for optimal water quality and enjoyment. One common challenge faced by pool owners is the presence of metals, such as iron, copper, and manganese, which can cause staining and discoloration. Eliminating metals from your pool water ensures stain-free and healthy swimming pool water.

CuLator Canadian Review

Hi David,

I want to take a few minutes of your time to let you know my appreciation and happiness about your product.

I am a French Canadian living in the country near Montreal. I have an in-ground hot tub since 1 1/2 year. I have been trying different products and different recipes without being able to get expected clear water.

Since I have used your CuLator Pak I have the most crystal clear water you can imagine and within less than 2 days.

You have to be proud to be part of a great company that sells exclusive products that for me are amazing products.

I have found about this product after talking to a Lawrason’s customer service person while I was exposing my problem.

I hope that you will become more well known in Canada to make more happy Customers…

Best regards,

CuLator SpaPak Question

CuLator SpaPak Question

Message: Hi,
I have recently purchased from Amazon a few packs of Culator for improving my hot tub water which contains metal from my well.
I would like to know if I can reuse it after 1 treatment. If yes what is the procedure to keep it for the next refill in 3 months.

Thank you
You do miracles!

Hello Michael,

Thank you for the email. 

Yes, you can reuse the CuLator SpaPak several times.  All you must do is rinse it with fresh water, let it air dry and then place it back in the skimmer (or where you place it) when you refill.  The CuLator polymers will get dry and crunchy.  This is normal.  They will rehydrate when you place them back into the water.

Thank you for the compliments!  Please let me know if you have any other questions.


My CuLator Ultra 4.0 swelled up! Is that normal?

Used CuLator Ultra 4.0 with Iron Trapped Inside

My CuLator Ultra 4.0 swelled up and filled the GatorEgg.  It looks like it is going to explode!  We hear this question all the time.  This is  normal.  Some CuLator Ultras do not swell up.  This is also normal.  Sometimes the bag may even have some polymers on the outside of the bag.  This is normal.  What isn’t normal is if the seams are torn or there is a hole in the bag.  If this happens, contact Periodic products at 954-764-7654.  Don’t worry, the CuLator is non-toxic and any polymers which ooze out of the bag will be caught by the filter.  The polymers will continue to work until you rinse off the filters.

Also notice that the colors of the polymers change depending on the metals trapped inside.  This is a great way to see if the CuLator is pulling out the metals from your swimming pool.

CuLator prevents stains by removing and eliminating stain-causing metals like iron, copper, cobalt, and manganese from pool water.

Filtering Rust, Iron and Metals with FillFast Filters

No problems!!  We love your product so much. Originally purchased (FillFast) to fill our pool but the guy on the phone said we could potentially install in our home to filter out the metals. So we did. We live in a rural area in Nebraska and have SO MUCH IRON it’s awful. Your filters are amazing. It looks like dirt but it’s METAL that your product kept out of my pipes. We are customers for life.

Used CuLator Filters used in FillFast Pre-Filter Removes Iron from Well Water.

We love emails like this one. In this case the customer used our 2 sump FillFast as a pre-filter for whole home to remove high levels of rust and iron. As you can see, the patented CuLator filter combo removes tons of metals. Call 954-764-7654 to discuss how we can help you filter out metals before they enter your home. FillFast is easy to configure to your needs as a pre-filter system to remove iron, rust, copper, manganese, and many other metals. The patented CuLator filters are easy to change out.

Well water contains many metals. FillFast is designed to remove high levels of stain-causing and corrosive metals like rust, iron, copper, and manganese.

CuLator Removed Copper From My Swimming Pool!

Thank you kindly for the information!  Historically, for the pool, I’ve simply used the CuLator 1.0 packet in my skimmer basket with good results.  I did try the CuLator 4.0 inside the GatorCage as an upgrade/replacement, but it did not seem to perform much differently.  Not complaining, but if the 1.0 is working, it would be simpler for me to just continue that routine.

As far as actual movement and lifespan, continuously using on of the CuLator packets has kept my copper levels fairly steady at 0.1 ppm.  Sometimes 0.0 and sometimes 0.2, but very flat.  I was north of 1.0 and going higher when I started using them just under 2 years ago when we bought the pool.  Previous owner did not unfortunately manage the water chemicals very well – pH way out of spec, ridiculously high chlorine and CYA, plus he added algaecide doses every week…

Everything is now in much better shape, but I think there is some damage to either the heater and/or copper pool pipes (underground) allowing them to leech copper still.  However, I do think it is getting better (reduced)!   Actually planning running for several weeks later this summer when I have a bit more free time without the CuLator to see how fast the levels are rising, but assume there will still be a need long term for the CuLator.

Thank you again!

CuLator with Copper Removed from Swimming Pool Water

Phoenix Arizona has Copper in Water

Phoenix, Arizona is dealing with a major copper issue in the municipal water.  When Phoenix residents fill their pools with city water, they are adding high levels of stain-causing copper, which can stain swimming pool surfaces or cause water discoloration.  

If you shock a swimming pool with copper in it, the pool water can turn bright green, or grayish or blueish stains can appear on the surfaces.

If the copper level is below .2 ppm, you should be safe from staining.  However, the goal is to have a swimming pool with 0 copper.  If your copper level goes up to .3, then you are at risk of staining all the pool surfaces.  

So, what can you do about a pool with copper in the water?

If you have copper in your swimming pool water, then you should use some Mega Maintain Sequestering Agent to suspend the copper in the pool water.  Next (at the same time) add a CuLator 1.0 to the skimmer basket or a CuLator Ultra 4.0 to your bump basket and let it remove and eliminate the metals from your water.  

What’s great about CuLator is that it is non-toxic and removes high levels of metals including copper, iron and manganese.  Those are the three metals which stain pools the most.  The other great thing about CuLator is the contents of our PowerPak bag change colors.  

What can you do if your pool is stained with copper?

We recommend using the Metal Stain Eliminator Kit.  It is a no-drain kit which removes metal stains, sequesters the metals (suspends the metals in the water), and removes or eliminates the metals from the swimming pool with CuLator Metal Eliminator and Stain Preventer.

How do I know my CuLator is working?

We get asked this question all the time.  The answer is to look UP at the CuLator with a light or sun behind it.  This will show the color of the metals removed.  You will notice that iron turns the CuLator a yellow color and copper turns it a blue color.  Sometimes you will see both.

The Results of Your Products Were Amazing! A Happy Customer!

It should be noted that I first tried Jack’s Magic Blue Stuff.  I was able to reduce the copper from about 3 to about 2 but that was it.  After a day or so, the copper level again increased. This was AFTER I replaced the brass ladder and the brass handrail with a new Safeco ladder and handrail.

The Jack’s rep was guiding me, but after the copper level increased, he told me that he could no longer help me and told me to get professional help.

That was when I went online and found Periodic Products.

The results of your products were amazing….as was your friendly advice.

I am a big believer in your products and I will always recommend your products and your support to my friends.

A happy customer!
