Pool came with house, best guess is it's not been maintained or run regularly for 3 or more years. It was dark green with chunks of algae floating around. Pine tree next door. Started removing pine needles with net.
Initialy added some algicide and ran filter, primarily to keep mosquitoes at bay. This changed the color to aqua for a while then it started to get green again.
Changed the sand in the filter, laterals look fine.
Got a simple test kit (Chlorine & Ph) and some dry 'shocker' as well as regular dry chlorine treatment. Hit the pool with the shock, kept chlorine level high with dry chlorine treatment. Removed about 100 gallons of debris and green sludge from bottom of pool using nets, garden hose vacuum and leaf trap/skimmer hose. Also added 'clear blue' at pool store reccomendation... pool has lots of foam: think I've got a suction side air leak that is making either the clear blue or the algicide foam :-/
At this point when I use the net or vacuums I'm no longer get anything green out of the pool and have to vacuum for quite a while to get much solid debris in the leaf trap. Chlorine seems to stay pretty solid... like no change overnight.
Still can't see more than 18" down. Water is cloudy grey. I've run the filter for weeks now, backwashing at least daily. Water remains cloudy. I've started adding DE to the filter skimmer after backwashing hoping to speed clarification. Pressure rises, but still no discernible change in the water clarity.
Finally got and used the TF-100. Here are the current stats:
FC - 5.5 ppm
CC - 1.0 ppm
TC - 6.5 ppm
CH - 125 ppm
TA - 50
pH - 7.2
Wondering what I can do to get the water to clear up more quickly?
