    Adding borates to an indoor pool?

    Is there any advantage / disadvantage with adding borates to an indoor pool that doesn't apply to an outdoor pool - ordor, cover issues, percipating out on the ground, etc. I finally have my CYA down to 25, the temp up to 84, and everything perfect but the CH - around 185 rather than 250. So...

    Need advice on what to add as I slowly reduce my CYA

    What's my Cl and pH - color test included.

    draining water.

    This is my first posting of a question, so I'm trying to explain everything. I need to drain some water from my pool. It's a plaster pool with a row of 3 2x2" tiles on the water line, so we keep the water level to the middle of tiles - 3 inches above the plaster. About one inch of water is...
