Have had the pool a ~5 months. After reading the forums things were smooth sailing and water has been clear - Up until I got a little lax over the past month and didn't do my routine brushing maintenance . It had been maybe ~2-3 weeks since last brushing (shame on me), although I've been keeping my water chemistry in check thinking that was enough and water has been clear. This past weekend I went outside to do some yard maintenance and saw the pool, which seemed to have some darkish black stains I've never seen before on the bottom. (2 separate spots, both about 5 feet by 7 feet each, spotty in nature). Didn't get a chance to take pics unfortunately, but immediately tested the water and came up with the following;
FC: 10.5
CC: 0
pH: 7.5
CYA: 100
TA: 100
CH: 500
Did some research here and confirmed what i was hoping to avoid, even with good water chemistry you can still develop algae without proper brushing maintenance. Did a small step up in chlorine addition as well as a thorough brushing (nylon) which brought up some expected small clouds, although mostly grayish in color. Seemed to be more sediment/dust than anything else. The following day I purchased a hybrid nylon/SS brush to go at it again hoping to break up anything that might be there, thinking if it was algae I would see my CC results rise.
I've been brushing daily, stain seems to be slowing dissipating, but my water results still have me a bit puzzled after tonight
FC: 13.5
CC: 0
pH: 7.5
CYA: 100
TA: 100
CH: 500
Additional info:
Weather temp in Norcal has been 30-50 degrees F. Water temp hovering in high 40s.
I know my CYA is high, inherited from previous home owner using tri-chlor tabs. Have been waiting for a weather forecast of 3-5 days of rain before draining to lessen our water usage footprint while also keeping the plaster damp throughout the process.
If it was an early algae bloom and I'm breaking it up with a brush, wouldn't it be expected to see my CC rise? I never went into SLAM mode, but wondering if it was an algae problem, how likely it'd be to combat an early bloom with proper water chemistry and rigorous brushing? If I do need to SLAM It would be sometime next week when the weather shows a few days of rain and I can partially drain and re-fill the pool so I don't need such a high FC level throughout the process
Thanks!
