I'm wondering how often I should fully replace my pool water? Asking around at the pool stores and the manufacturer of my pool, everybody says I should drain and refill the whole pool every 4 years. If my numbers are all within range, i.e. TA, CH, and CYA, how often should I do a full drain and refill? Do I even have to do a full refill?
I see quite a few threads on pools that are very dirty, algae infested and so on that are getting told to SLAM. If a person even moves into a house and finds a very green pool, still the SLAM process is advised. Wouldn't it be easier for a person in a situation that doesn't know how old the water is to just drain and start over?
I find myself at the 4 year mark and my pool is sparkling clear and I think why fix something that isn't broke? I guess I want to find out from the experts on this fantastic forum if I ever really have to drain if my numbers are in range?
