CuLator Solves Copper Cyanurate Problems in Swimming Pools

We received a question from a customer who had purple gunk at the bottom of his swimming pool.  We suspected that he had copper cyanurate.  We had him check his CYA level which was very high.  His copper level was also very high.  High copper + High CYA = Copper Cyanurate.   We had him drain the pool water and refill until the CYA was between 30-50.  When he drained the water, there was a light purple residue (sand) which showed up on the street pavement.  Obviously, that purple sand was copper cyanurate.  He was instructed to add a CuLator Ultra 4.0 to his pump basket and the problem was solved.

Here is what was said in his own words:

Here are the photos of our pool. The last two photos show the residue that accumulated in the street at the end of the vacuum hose. The numbers are looking great; we will be placing the CuLator Ultra 4.0 cartridge in the pump basket this evening! 

Once again, thank you for all your help. I look forward to doing business with you in the future.

Pool closing…thanks for all your help this Spring with our “Purple Haze” problem. We survived the summer with pristine pool water and no problems.

Why does the CuLator Ultra 4.0 Swell Up?

culator metal eliminator

When CuLator is added to the skimmer or pump basket, it usually swells up and becomes very puffy. This is normal. The best way to see if the CuLator is catching metals is to hold it up to the light. In this case, there is some blue at the top showing that the CuLator is binding copper out of the swimming pool water and preventing stains..

 

 

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

Ultra PowerPak 4.0 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.

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!

Thanks,

David

Before CuLator and After CuLator

Fiberglass pool treated with NO-DRAIN Metal Stain Eliminator Kit and CuLator Metal Eliminator

before-and-after-blain-pool

Here are images from a customer who used a No Drain Metal Stain Eliminator Kit on an in-ground fiberglass pool.  The pool was completely stained, but the stains were lifted, sequestered, and eliminated with a CuLator Ultra 4.0

 

What is interesting about this pool is that we noticed that there is no metal touching the water.  So, we asked the pool owner if the water was bonded (which equalizes the electrical potential) and he found out that his water was NOT bonded.  Once he bonded the water, his metals were not immediately plating out onto the surface.

You not only have ground your pool equipment, you must also bond the water.  Yes, these are two different musts.  Many new fiberglass pools are not bonded.  Please check your pool!
