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 Solves Copper Cyanurate Problems in Swimming Pools
What’s That White Stuff On My CuLator Bag?
When CuLator is placed in the skimmer basket (or the pump basket), and you use a phosphate remover (or a weekly maintenance which contains a phosphate remover), the phosphate remover can collect on the outside of the CuLator bag. This does not interfere with the working of the phosphate remover nor the CuLator product. It just looks ugly because it looks like a white goo that resembles Crisco. If you see this form on the outside of the CuLator bag, just rinse it off. Some examples of phosphate removers are Natural Chemistry Phosfree, Orenda PR-10000, Leslie’s Pool Perfect Weekly.
What are the little black spots in my fiberglass pool?
When you see little black spots on your fiberglass swimming pool, it could be a few things. First, try to remove them with a vitamin C tablet. If that doesn’t work, then have your water chemistry tested to see if you have a high phosphate level. If you do, use a phosphate remover then balance the pool water to see if that solves the problem.
Cobalt can also cause spots like these. The gel coat delaminates a bit from the surface and these spots can develop. Just place a CuLator Ultra 4.0 into the pump basket to see if that lowers the metal level to remove the staining.
Gel Coat delamination does happen with some fiberglass pools. Check with your pool manufacturer to see what they can do, but doing a phosphate, or stain treatment is much easier to deal with.

Why does the CuLator Ultra 4.0 Swell Up?

Why does the CuLator Ultra 4.0 puff up? The CuLator polymers “hydrate” when they enter the water and puff up. As they bind the metals out of the pool water, the CuLator bags will “shrink” back down to a much smaller size. So, when is CuLator finished? It is easier to tell with the Ultra 4.0 because the bag will be about 1/2 full, or the contents will feel watery inside or they will feel sandy. With the 1.0 it is a little bit harder to tell, but when the bag feels almost empty or there is a lot of color in the bag after a month, then it is exhausted.


Opening Your Pool with CuLator Metal Eliminator
When you open your pool here are a few hints:
- Place a CuLator Ultra 4.0 into the pump basket and run a few days before adding any swimming pool chemicals (as long as the pH is above 7).
- Leave the CuLator Ultra 4.0 in for the entire summer to grab metals out of the water and keep your water clear and to prevent staining.
- If you are worried about any metal levels in the water, add some sequestering agent to the water to hold the metals in suspension until the CuLator will pull them out.

Review of CuLator Metal Eliminator with Before and After Shot
This pool was greenish from oxidized iron and lower alkalinity. After the chemistry was balanced and a CuLator Ultra 4.0 was used to remove the metals from the water, the pool stair stains were gone, the cloudiness was gone, and the metals were out of the pool water.
Here is the review:
Hi,
I placed the CU Lator in the skimmer basket last week. The results from the test at Leslie’s is no copper. The chlorine and other test items were just about ok. So yesterday the family used the pool.
I want to thank you for the product, CU Lator, and the kind and attentive assistance you gave to me in getting my pool dilemma resolved.
Now I will have to learn how to balance the pool chemicals, so it does not repeat again.
Thank you again and have a nice day.

Use CuLator Ultra 4.0 to Remove 0.4 Copper from 31,000 Gallons
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!
DC
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! Thanks, David |
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.
The clear sump allows you to see what metals the CuLator is removing from the water.
Here are a few examples of used CuLator Metal Eliminator Filters:


Once the filters are used up, you just replace them with a new CuLator Filter. Continuous metal removal is the best way to prevent metal staining on your pool surfaces and to prevent water from turning brown or green when you shock.
CuLator InLine Pro is available through your pool professional only. Call 954-764-7654 to learn more.
