We have owned our house w/pool for 8 years and we have never had a year like this. We desperately need some help.
Our pool is a 20,000 gallon inground pool with a , vinyl liner, 1hp motor, a Hayward S200 sand filter, a Hayward H200 heater, and a Hayward vari-flo valve.
We get the pool started up and it is looking quite green, pretty much like all of the years we have owned it.
We let the pool run for 24 hours and our pool store gives us 10 gal. of liquid chlorine, a bucket of stabilizer, and a thing of algaecide to open the pool and asks us to come back with a water sample.
3 days later the pool is still very green, I bring in a pool sample and they give me another 10 gal. of liquid chlorine, a bucket of stabilizer and another thing of algaecide.
A week later the pool is light green, but still so cloudy you can't see the bottom.
At this point we are going on two weeks and are confused and frustrated.
My wife takes matters into her own hands and does much better than the pool store. She found that the alkalinity was high and the PH was low. She first adjusts the alkalinity and then adjusts the PH. Yesterday for the first time we put in 3" pucks and shocked the pool with 4 bags of hth super shock.
I know it has only been 24 hours since we shocked it yesterday, but it has been 3 weeks since we have opened the pool. We are tired and I am about a week away from filling it with dirt and building a nice playground.
Also this afternoon my wife was vacuuming the pool and notice green water coming into the pool from the returns.
This morning it is better, but it is cloudy and light green with the following chemical readings:
Free Chlorine - 3
Alkalinity - 100
PH - 7.8
Stabilizer - 30-50
So far we have added:
20 Gallons of liquid chlorine
2 Containers of stabilizer
2 Jugs of algaecide
4 bags of hth shock
3 3" chlorine tabs
This is very abnormal for us, typically we open the pool and in three days it is clear, balanced, and swimmable.
