Long time since I was last on this forum and since then, moved across the country and built a new pool
Our pool was completed in August 2015 and is a 15K Gallon IG, Pebble sheen pool with spa and water features. We previously had a 25K IG Vinyl and were located in PA before moving to TX.
With all that said, our pool has been eating acid like crazy. It was stable for the first six months of existence, requiring very little to keep things in check. The past four weeks have been a different story, where the PH is high every day. Usually takes 12-24oz of muratic acid to get it back in line only to have it high the following day. Our pool does get a good amount of aeration, so I am not sure if that combined with the new pool is causing it or what. Here is a look at our numbers from today (and this is pretty consistent)
PH - 8.0 (Acid demand 1 drop)
TA - 100
CYA - 30
FC - 3.0
CC - .4
CH - 210
Recently I've had the chrome on the pool lights get cloudy/scaly and also a big white crystal formed under my water feature that I had to chisel off. The stone wall is a waterfall as well as the stones on the beach entry.
