The Famous Green Pool After A Storm

[holubec37]

We recently moved into a house with a green pool. I immediately installed a SWG and started the SLAM process. In less than 2 weeks the water passed the OCLT and I dialed in the SWG % and got the pool into “cruise control“. I was headed out of town for work for a few days so my wife asked what she needed to do pool-wise, so I said just make sure the pump comes in and throw the Triton in Monday morning. Sunday night there was a large storm (lots of stuff from the yard washed into the pool) and she woke up to a “brown” pool. I got home last night and took a full set of readings this morning.
FC/CC 16/0
pH 7.4
TA 80
CH 120
CYA 65

I had her test on Monday and the pH was around 8 and I had her add 3 lbs of CalHypo 75% to increase the amount of FC till I could get home.
The water was balanced as per the Pool Math ranges, although I was working on lowering TA from the high side of the range due to quickly rising pH levels.

Unless there are better ideas, I’m starting the SLAM process again.

While your chemistry looks OK, could this be more of a filtration issue? Have you cleaned your filter and let it run. I know after strong storms down in Houston area, I have lots of debris and it just needs to filter out. So I clean my skimmer baskets every couple of hours (I sometimes put socks in them to catch very fine debris) and also clean my filter. It may take a day or 2 but if I keep my FC on the high side of the range (not at SLAM level) and run my pump continuously it will clear up.

I’m hoping is just filtration. I brought up the FC to SLAM level and will do the OCLT and see where I’m at in the morning.
