I've been reading the various forums trying to diagnose and find a solution to my problem. I think I have calcium scale buildup on my vinyl liner. Here are the details and test results...
I am currently running a Autopilot SWG. For the past 2 months I have been out of the country and my wife has taken over pool maintenance duties. Unfortunately she been listening to my neighbor and has been dumping two 1lb bags of POOLIFE Turbo shock (Calcium Hypochlorite 78%) every 5 days. The water is clean, but this is a fine layer of white covering the bottom of our pool (but not the sidewalls). Plus, there are several brown algae spots that I just can't brush away. I think they might be algal/scale deposits??
Here are my test results (I know I need a more comprehensive kit, so I have just ordered one) :
FC = 1.75ppm
pH = 7.6
TA = 130
I'm wondering if I add muriatic acid and lower my pH to 7.0, if that will help soften the gritty white layer so that scrubbing will be more effective. If that works, what are my next steps?
Any advice would greatly be appreciated. Thanks!
