We are trying to clean our pool which hasn't been opened in two seasons.
We are near Philadelphia, PA.
Pool is concrete and it had a solid cover on it and was correctly winterized.
Filter is the type that takes DE.
Pool is open and pump going - we are backwashing twice daily as pressure builds.
Estimating 20 - 26,000 gallons.
We got all the debris off the cover before removing and scooped most of the debris from the bottom (although we still can't see what is left).
We added 20 lbs of Aqua Chem shock over several days and still weren't getting a chlorine reading (although the frogs moved out!).
Chlorine tablets floating in a dispenser. Still no chlorine reading.
Yesterday added 5 gallons of sodium hypochlorite 12% in liquid form and now have a chlorine reading.
Today we had the pool water tested and got the following results:
Free Chlorine: 0.4 ppm
Total Chlorine: 4.62
Combined chlorine: 4.22
Hardness: 152 ppm
Alkalinity: 100 ppm
Cyanuric Acid: 30 ppm
Copper: 0.2 ppm
Iron: 0 ppm
We have been getting help from an awesome and very knowledgeable guy, but wondered if anyone had any more ideas as to why the pool is staying murkey?
Pool store is recommending:
8oz Les Iron
1 lb PH up
wait 24 hours and add 2lbs shock.
