I recently put up a Proseries 14'x42" AGP with skimmer and 1000 GP pump. Pool holds approximately 3300 gallons. I had low ph so I wanted to bring it up. I used the Pool calculator and came up with the amount of borax to add to bring the PH up from 7.0 to 7.6. Added it and tested the following morning. The PH was off the chart. In looking at the calculations I found that I forgot to change the gallons on the pool calc from 10K to 3300. So I put in 3 times the amount of borax needed. So to fix I have added 5 oz of HTH ph minus. After about 10 hours tested again the PH was still off the chart with virtually no change. I have since added about another 8 oz's of PH down and am now waiting to test again. My question is after adding all of the borax to the pool will I need a huge amount of PH minus to get the PH back in range?
Other measures are:
