Good Day.
First full year with a 10 year old AGP. All going well this summer here in Michigan. We installed a heater this year, replaced (and increased from 16" to 24" sand filter). There has been no real issue with algae. I have been having a hard time ever getting any FC when I test (K-2005). The pump/heater turns on about 10am and turns off around 8pm. Typically I think can see underwater across the pool with no problem (17') (never really thought to keep a mental note of actual viewing distance -- will do now).
I routinely vacuum the pool on Fridays, and test at that time and on Wednesdays (using the TFP Pool Math app to tell me what chemicals to add). All summer long I have never had a reading of FC (always zero).
Last Wednesday, started 3 days of good rain and I didn't get to vacuuming nor testing the water.
Saturday came and there was green-ish algae starting to grow on the bottom. So, I vacuumed well, brushed the walls, and added 2 gallons of chlorine per Pool Math and one pouch of Clorox Slam Step 3 pouch -- chlorine and algaecide). I've left the pump on 24/7 since Saturday (but turning the heater off over night). We are still swimming, and all "feels" and smells okay, but the water is definitely the cloudiest (more of a white rather than green cloudy) that I've seen it this summer.
Sunday I tested again, vacuumed again, and backflushed and rinsed the filter (it didn't look too bad). I also added about an inch of fresh water Sunday night as the level was getting toward the bottom of the range on the skimmer (city, hard water). While swimming later in the afternoon, I could definitely smell the chlorine.
Today, Monday, the water looks better than yesterday (less cloudy) and the Pool Math told me to add another gallon (121 oz 8.25%) of bleach. Tonight while swimming there was some algae on the floor, not a lot. Still white-ish cloudy. Today I actually had a FC level. Didn't notice any chlorine smell.
Any thoughts or comments appreciated. Attached photo is tonight at sunset. I would have taken a picture of the algae, but we've been swimming and I made sure to go all around and "wave" the algae away so that it would be suspended.
Thanks.
PS. Pool Math app -- as I go back and look at my logs, it doesn't appear that I can access what the recommended levels of chemicals it suggested.
