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.
