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.

Iron Bacteria Eliminator Kit Worked!

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!!!

Before CuLator and After CuLator

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

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!

Here is a great site about Pool Water Bonding.
