Is it true that the only way to reduce a cya level of 150 is to dump several feet of water from the pool and replace with fresh water?
I have a 16 x 32 vinyl lined pool so I believe I can only dump about 2 feet of water at a time to keep the integrity of the liner in tact. Does this sound about right and how many times do you think I would need to drop the level and refill before I get cya levels down to around 40 or 50?
Thanks for any replies.
