Last summer we were not able to use our pool because we could never get it balanced and the pool company sold me 100's and 100's of dollars worth of chemicals and chlorine (which it ATE but was never effective) that I think only made the problem worse. I started this season by giving the pool store one more shot but quickly realized we were on the same spending and frustration track as last year. I spent the past two weeks educating myself here at this forum (Thank you SOOO much) and have purchased the PROPER testing kit FAS-DPD and have begun the process of trying to make our pool useable again.
We have a 10,000 gallon vinyl pool (20ft round by 52" deep)
It used to be on a Tri-chlor auto feeder cartridge system. (Which worked well until last summer) I am switching to 12% liquid chlorine, the BBB method.
The pool gets constant, intense, direct sunlight as it is in the middle of a large open area. No shade at all.
We have a cartridge filter system, the cartridge is new.
The first problem I had was an overload of calcium hardness in the pool. This weekend we drained 1/3 of the pool and had fresh water delivered to replace. My new CH number is 350-375. I can't afford to replace more water at this point.
There is noticeable scaling on the vinyl liner.
These are this mornings numbers:
CYA-20???? I am guessing here as the test was inconclusive. Before the water replacement we had a CYA of about 30-35.
My plan for the day is to add Borax to bring the PH back up according to amounts rec. in the pool calculator.
Then tonight I am going to superchlorinate according to the 30PPM method listed in the table in the instruction manual of the pool testing kit by adding 2.5 gallons of 12% chlorine.
The pool is a lovely shade of cloudy turquoise.
We all desperately want to see the bottom of this pool.
If anyone has any advice or reccommendations I would love some input.
My kids are counting on me and I don't want to let them down again this summer.
Thank you ever so much,
