Browse Forums Pools & Spas Fiberglass Pool Bleaching under the water line 59Dec 02, 2019 2:06 pm It is not just 1 gel coat supplier and the problem is world wide . I have had been part of some local,testing for a American chemicals co . The fact that it is random puts more weight to claiming it is water ballance . I have core drilled a fibreglass pool Wh bleaching and sent to a lab to try to determine cause . I couldn’t get a definitive answer . It could of been chlorine bleached or could be under cured .
My recommendation is to get a automated water ballance system which constantly adjusts and records levels every few minutes such as the Omni logic system . Then it is impossible to blame water ballance . Re: Fiberglass Pool Bleaching under the water line 60Dec 02, 2019 8:20 pm Thankyou for your comment and the recommendation of the Omni logic system I have just had a look at it and although it seems to be good on the surface. I dont think (on first read) that it measures the alkalinity. This is one of the problems when the alkalinity reading goes below 80, the pool owner will need to add more "Buffer" this in turn increases the "ph" and then the pool owner adds more acid to bring the "ph" down and this also brings the alkalinity levels down and so the cycle continues and I have proven that it is definitely beyond my constant readings of the pool I cannot maintain the the 80-120 Alkalinity and a PH of 7-7.2 . It is impossible for me anyway, I would love someone to prove me wrong. And with the Omni logic system I cannot read anywhere where it maintains both of these levels (and also I presume it works off of sensor probes) which again would require calibrating and regular maintenance and replacing at some point. I am not putting the system down, but any automated system that is added to the pool, evidently pushes the owner away from the responsibilities of looking after the pool (makes them more relaxed) as they are told that it is fully automated and they dont need to worry. This is when things can go wrong if the system is left alone for too longer time period. Thankyou for your suggestion though. And yes it may be a faulty gel coat, or down to under cure, or down to the on going maintenance of the pool owner. As these 3 things are very hard to prove (apart for the pool owner) the pool owner normally gets the blame. Thats why we are all here .
