Please help … I’m at a loss. Do I need to SLAM? I feel like I’ve tried everything. First, the numbers:
FC 8.0 (Target 3 to 10 according to Pool Math App)
C.C 0.0
pH 8.0 (Just added MA to lower to 7.2)
TA 70
CH 370
CYA 70
Salt 3400
Temp 84° F
CSI 0.13
SWG 50%
Pump Cycle: 10 hours (8 AM – 12 PM @ 2400 RPM, 12 PM – 6 PM @ 3000 RPM)
The problem: About a week ago, the water began to look slightly cloudy and greenish (not full on green). I began to brush daily. When brushing DAILY, I get a light dusting of greenish/brownish dust from the bottom on the pool. Initially, I thought, “Oh no! Algae bloom!” Then, after reading and thinking about changes, I waffled and said, “Maybe it’s oxidation of iron in the well water.” Now, I’m back to algae bloom. It hasn’t gotten worse, but it hasn’t really gotten better.
Prior to this occurrence, I was brushing and vacuuming every 3 days and cleaning my filter weekly. I have stepped up to brushing/vacuuming daily and cleaning my filter every 2 days since this has occurred. When I clean the filter, it does appear to be collecting the green residue, but it isn’t overwhelmingly dirty either.
History: The pool was getting low and we hadn’t had a drop of rain in f-o-r-e-v-e-r. So, about a week ago, I added approximately 2 inches of water to the pool. We are on a well. My fill water does not go through our water softener. I fill from a hose bib near the pool deck on which we have installed a large charcoal filter.
I have tested my Chlorine daily and it hasn’t dropped below the minimum. The lowest it has tested over the last week was FC 7.6 PPM. I have done the OCLT twice during this period and there is no change – no loss of chlorine is showing. But, of course, the water isn't sparkling.
Previously, my TA was reading 60 PPM – a scant 60 – it was flashing at 50, but not holding. Two days ago I began raising my alkalinity with Baking Soda. I didn’t have enough on hand, so I added what I had and added the remainder needed yesterday after going to the store. It is now a solid 70 PPM.
I adjusted my pH this morning. My pH regularly goes up – I’m told because we have a SWG. I typically need to add Muriatic Acid about once a week to keep it in range. So, it has been steadily climbing through this process, but hasn’t been too high or too low. I generally let it get to 8.0 before adjusting it back down.
Of note: I do not add anything but TFP “approved” chemicals to the pool. Although I must go to the pool store to have my water tested monthly for my equipment warranty. Their numbers rarely match mine, so I smile and nod as they tell me their recommendations and tell them I’ll work on that.
Please help! Thanks!
