6000 gallon dog therapy pool (plaster). My plastic cover blew away and the pool got fouled with quite a bit of leaves before I returned. October) I've fished them out; running the 60 gpm pump (cartridge) 2 days. Can't seem to get the discoloration out of the water. Tannic acid, I suppose. Can't use anything that dogs can't drink. Any thoughts? Dumped in 6 gal bleach. Immed before that, ph was at 7.0.
got broken dogs waiting for the pool.
PS 4 feet of water is color of weak iced tea.
