Pool owner going on two years now and just starting to understand water chemistry thanks to this site. Admittedly, we have slacked on brushing the last two weeks with a newborn at home, but it seems like the walls have turned green within the last couple of days. Had time to scrub the entire pool tonight by hand as far down as I could reach and then the brush on the extended pole after that. Looks much better, but obviously the water is no longer clear. I thought I needed to SLAM, but by CC levels are less than 0.5ppm. Results from tonight's water testing:
PH = 7.7
FC = 2.5
CC = <0.5
TA = 110
CH = 300
CYA = 30
Short history that may be relevant. Drained pool in May for an acid wash prior to opening (suspected scaling resulting from what pool store tests indicated absurdly high levels of CH, likely a result of the prior owner and me initially relying on their suggestions to add Calcium Hardness increaser and shock every other week). Surface looked great after the acid wash and we filled pool from hose with city water. Water has been crystal clear up until earlier this week, but I do need to add 16-32 oz of Muriatic Acid each week. For chlorine I have been using a combination of trichlor tabs (been trying to slowly bring up CYA levels) and liquid bleach. I've been running the pump at least 7am to 7pm. Here are my prior two tests since receiving my TF 100 test kit earlier this month.
July 9th:
PH = 7.8
FC = 1.5
CC = 0
TA = 100
CH = 250
CYA = 20
July 4th:
PH = 7.2
FC = 7.0
CC = <0.5
TA = 110
CH = 250
CYA = 20
Based on tonight's testing, I added 16 oz of muriatic acid to bring the PH down below 7.5 in the event I do need to SLAM and left the pump running overnight. I know my Chlorine levels are low, so was going to add the liquid bleach tomorrow after giving tonight's acid the night to mix in to bring my FC up to 4. What should I do after that? Just maintain my FC level at or around 4ppm or should I SLAM? Help please!
