So having done a lot of reading around the subject I ordered the TF-100 test kit and completed my first tests this morning.
pH 8.2 (I know this is high - what do I add to lower it?)
It seems that the CYA and FC combination is acceptable from looking at the CYA - FC chart, although I should be targeting slightly higher. I have a Pentair Rainbow 320 chlorinator that was set at 3. Increased that to 4 today to try and up the FC a bit.
I think CH is OK?
Main concern is the high TA and high pH - recommendations on what I need to do to rectify that.
Pool is inground plaster pool and was completed approximately 4 weeks ago. 19000 gallons with raised spa with spill way.
I had the water tested at SunTex pools two weeks ago. Results from that test were:
On their recommendation I added 1 gallon acid and 60lbs of Proteam Supreme Plus (in 3 equal doses, each a day apart). They did comment that the FC was low but recommended not shocking a new plaster pool (?)
Recommendations on what I now need to do would be much appreciated
