Hi all - thanks in advance for everyone who has made this site such a wealth of information.
I have a new construction pool (specs in signature) that was finished late last fall and immediately winterized. It was opened early for our area (New Jersey) on March 31st, and has been crystal clear up until the last few days. While I thought my CYA had gotten up to 70, I'm now realizing I may have been too generous with considering the dot no longer visible. Using the at-a-glance advice, I suspect I'm actually at a 50. I'm not sure how to link my pool math results here (as I've seen others do) but here's my numbers:
FC 4.5
CC 0.0
PH 7.8
TA 70
CH 125
CYA 50
While I thought I've been at an ok FC level for the last few weeks as we've started to heat and swim in the pool, I suspect 4.5 doesn't quite cut it. I was at a 4.5 FC level yesterday afternoon, so this morning I added 64oz of 12.5% liquid chlorine. The above test results were taken just a few minutes ago, so the bump I thought I'd get appears to have been consumed but I'm surprised I'm not seeing any CCs if I have an algae problem.
I can still see the bottom of the pool and it doesn't appear to be getting any worse, but it's not like it used to be where it was stunningly crystal clear. As far as action items, I believe I may want to add some more stabilizer to get my CYA up, and add some muriatic acid to drop pH a bit. But what should I be doing as far a liquid chlorine. Should I be doing an over night chlorine loss test? Should I be running the pump over night? Currently my pump is set to run @ 2200rpm from 8am-8pm.
Obviously this is my first season with the pool, and it was feeling too easy but I thought I just did enough homework ahead of time! Guess I still have some learning to do! Any advice on what I should be doing is much appreciated! To be honest, I'm not sure what my situation is, which makes it more difficult to search how others have approached a solution. I've attached a photo of the pool to the extent that's helpful. I feel like it doesn't fully capture how cloudy it is but I suppose to only limited reference point is how it's looked the last two months.
Thank you!
