So I live in South Florida. To us it was cold this winter and we did not swim for several months
During that time I floated chlorine tabs open full in the dispenser and added powdered chlorine about 1 lb per wk of Sodium Dichloro Tri dihydrate.
Tried using a Ca based cholorine (leslies brand free and clear) last year but ended up having problems with ca levels.
This is a 15.500 gallon kidney shaped pool
Standard story. small amounts of alge were seen with high cholorine levels +5 on my cheapie reader. (actually 8 to 10 was the reading from store tests)
Added more powder cholrine to fight the growth.
Took a sample of the water to be tested and yes the cya was +150. said they did not have a test that went higher.
I drained 2/3 of the pool waited 48 hours and retested. It remains at 150.
I have now drained the pool again 2/3 and am now refilling. I dont want to do a total drain as in Florida I dont want to ground water to push the pool in any more than it has to be.
The question is this
I am going to stop using powdered, and switch to liquid. I dont want to use the tabs any longer
Once filled I am sure the cya is probably still going to be around 80 to 100.
Using only liquid chemicals and calculating the rain do you think I can get my cya level down to a good level without another refill???? Between 30 to 50??
I have read that cya can only be removed by drain and fill.
Water is expensive in FL so far I have probably hit a bill of 300 for this month.
Do you reccomend using only liquid chemical for the pool?
Thanks everyone. I have been reading up on this since registration but cannot find the best answer.
