Hello Forum Members !
I'm new here, and hope to contribute soon but need a little help to get going.
Most of the summer has been trouble-free, but I went away for a week and came back to a cloudy, out-of-balance pool which I suspected as being in "chlorine-demand" based on previous experience. Test strips were difficult to read.
I added chlorine until I got a total and residual reading over 5, about 32 gallons of 12.5%, but in a couple of hours it was back to near zero...and I ran out of chlorine on hand
I will buy a good test kit, but meanwhile took a sample to a Bioguard dealer for computer analysis, results as follows:
Adj. TA: 82
Total Hardness: 130
Water is clear, 82degF. I'm using PhosFree to reduce phosphates. Per the computer analysis recommendations,
I've added 25 lbs of NaHCO3 to raise alkalinity and am about to add 6 lbs Na2CO3 to raise pH.
Is there a calculation on this forum of how much chlorine will be needed at this point to correct the pool ?
Pool store says I need 55 gallons of shock to overcome the demand, but from reading these forums (fora ?) I understand it could be a multi-day process.
I appreciate your help !
