Hello -- first time posting. We have a 12-year old pool in No. Calif. For about the last year or two we have had increasing green algae, powdery/sandy substance collection daily on bottom of pool, excessive chlorine consumption, and cannot get it to balance, continues to need more and more soda ash. The plaster is beginning to erode, is very rough all over the place so I do believe we need to replaster but I also think that from what I read on this forum, the use of trichlor/dichlor floating auto feeder tablets (which we have done exclusively for all 12 years, daily) has caused some of the erosion and problems with have with balance and algae.
So here is my question, once we invest in replastering the pool using DiamondBrite this Fall, what are the best ways to keep a well-balanced, pool with good chlorine levels? When it was a new pool we did not have any of the problems we are seeing now. We would just put a few tabs in the auto chlorinator, add some liquid chlorine and acid about once a week and things were great. Now, can't get it balanced, horrible little bugs that bite in it all the time, lots of green algae, and needs to be shocked all the time to get it to good levels. Very discouraging.
We don't know anything about this topic of CYA levels but it seems pertinent from what I am reading.
