I had to go to the pool store today to buy some calcium chloride. Was talking to the store owner about the ugly organic stains on my walls and floor. I have already done the slamming process for 2 weeks as recommended by one of the tfp experts, but it didn't help with the staining. He said they acid wash pools all the time just by adding 3 to 4 gallons of muratic acid to the pool water and then let it circulate through the pump and filters for a couple hours and then shutting the pump off and letting the pool water sit for a couple of days. Then neutralize with baking soda afterwards. Has anyone ever heard of doing such a thing? Would this process do any damage to my DE filters or to the pool pump or plumbing? Thought I would ask y'all as there is much valued knowledge here.
I don't want to drain the pool to do an acid wash since we have had a lot of rain and I don't want to float the pool.
