Ok in a matter of days my clear pool went cloudy green, I am on BBB and these are my #'s when it first started turning
PH 7.8 Pool Store said 7.9 ( I wanted to double check my #'s and they just told me to shock with liquid chlorine as I did)
CYA about 75
I have been shocking to 25 for 2 days now and brushing and vaccuming. Not sure what is going on, it is a light green and I can barely see the bottom, should I flock it or whatever? When I shocked on Saturday, I came back Saturday night and about 2 feet from the wall all the way around was my blue liner and all the **** was in the middle, thought that was odd.
Now here is an observation.
Neighbor put up I would say 18 ft intex pool, as they were filling on Saturday it had a green tint, Sunday. Still Filling, Monday as green as mine on a fresh fill. We have city water. I am wondering if maybe I have metals in my water, since once I shocked it got cloudier, I shocked with 12.5%. I have been draining water out and adding to lower CYA.
Pump is running 24 hours, I backwashed twice and was expecting to backwash green, but it was brown for a few seconds. I am not seeing sand or piles of dirt on the bottom which would suggest to me it was pumping it back in. I also ran my pool rover and he is getting brown in his bag but not much, whatever it is the regular vacccum will pick it up but Rover just glides over, I have been running him if anything for circulation when I am home.
