I bought a house two days ago and have a cloudy green algae problem the pool is salt water 16K ingound vinyl liner.
I know I need to order a good test kit and will do so later today.
I took my water sample to the pool store and my levels are below
FAC - 6
PH - 7.8
TA - 110
CYA - 30
Salt - 4000
Phosphates - 100
I placed in 2 Lbs of Aqua Chem Shock Xtra Blue for Swimming Pools 2 days ago and it seems slightly better.
I have been doing some more reading on this site including the Pool school and using the calculator. My plan of attack for now until the full test kit gets here is to buy a test for Free Chlorine and add Liquid Bleach to keep the FC at 12 until the pool is clear.
