We got back from vacation 2 weeks ago & I'm still struggling to get my pool back in shape. Before we left everything was fine. I went ahead and shocked the pool before we left & had my neighbor add bleach every other day. Apparantly that wasn't enough because we came home to a partially green pool. So I shocked, brushed, vacuumed, filtered, tested water & repeated as necessary until the chlorine held overnight & there was minimal CC.
Things seemed to be going fine. I am trying to remember the POPP, but things just don't make sense to me. Here's what keeps happening:
The pool gets to where it's mostly clear, but there's what I'm guessing is dead algae on the bottom. It brushes & vacs up easily & then the pool gets cloudy. I rinse off the cartridges after I vac & let it run 24/7 thinking it will suck up whatever got stirred up. After a day or two of cloudy water it's back again on the bottom - pretty much evenly across the entire pool - almost to where you wouldn't know anything is there until I run the vac or brush over it. Then I'm like - there's the nice blue bottom I've been missing, but AUGGH the water's getting cloudy again.
I have been suspicious of new algae growth, but the numbers say otherwise - no CC & chlorine holds overnight. The other mystery that makes no sense to me is my CYA. Up until this problem it hovered between 30-40. Last week when I tested it was at 50. I thought maybe it's because of cloudy water??? This morning's test showed around 60. The water is not cloudy right now (I'm in the everything's on the bottom phase) & I have only added bleach throughout this whole process.
What am I missing? Doing wrong? My next thought was to vacuum to waste & skip the filter all together.
Here's my numbers from this morning:
FC - 3.6 too low if CYA is really 60
CC - .2
pH - 7.8
TA - 70
CYA - 60 during this period, had been 30-40
Temp - 80
We've been getting rain just about every day - been a very wet June.
I welcome all help, tips & advice.
