    Customer has a 15000 gal pool that's been down for a while. It's not green, but is cloudy. They're trying to clear it up, but before they can SLAM, we're trying to get the pH down. The muriatic acid seems to have little effect, and I'm suspecting an air leak. Tests are as follows: Date ph TA...

    Is there any downside to raising ph using aeration?

    Hello, After watching this video I tried/tested sticking the outlet of an industrial vacuum cleaner into the pool and that created a lot of turbulence (literally like a volcano erupting). ph is currently sitting at 6.8 (or thereabouts, it's a bit hard to tell as test is limited at this level)...

    Naturally rising pH?

    Hey all. I have a pebbletec, 27k gallon pool, cartridge filter. When I moved in in February, it was my first pool, and a friend of mine who works in the pool industry recommended and helped me install an inline tab feeder. After following this website for a few months, I decided eleven days...
