Began using the TFP method last year, and it has been a life changer for us. I now religiously test and treat the pool to ensure I keep it balanced, and it has been wonderful. However, I've been struggling for a couple of weeks with a slightly cloudy pool. It's almost clear but not sparkling like it has been since switching to this method. We also get an accumulation of a light rust colored solid after one night. We can vacuum it one day only to have it accumulate again the next day. I've attached a pic of what it appeared like today after vacuuming yesterday. It is a very fine solid, dispersing with the slightest touch. We are being careful and slow when vacuuming to try to reduce dispersing. We have a few pine trees that drop some straw, but they haven't been dropping much lately.
Here are my measurements from today before vacuuming, with some care details as well:
CYA: 50 --I try to target 40, so a bit higher than I want.
FC: 8 --Targeting 6-8 and have let it get no lower than 5 or so in the last several weeks.
CC: 0
pH: 7.8--on the high end, added Muriatic today to bump it down.
TA--90
Pool Essentials 10% bleach (WalMart)
I run my pump about 8 hours per day.
I typically add the bleach in the afternoon, ensuring at least 30 minutes before allowing pump to go off.
Replaced filter sand last year.
I shocked last week, even though my numbers didn't indicate the need, but I didn't measure it every few hours after. I shocked today and am going to stay on top of it until tonight.
Is it possible that these solids are some sort of algae? I would appreciate any help anyone can offer.
Thanks.
