So I have been reading as much on here as I can, but some of what I just tested on my water leaves me scratching my head.
14,700 gallon vinyl above ground.
For 3 years I opened with pool store recs and ran a salt generator with no problem. Last year it went to pot.
Pool is green but vacuumed. I vacuumed and put 1/2 gallon of 8.25 bleach in 2 days ago and have been filtering waiting for my nice new FAS-DPD kit to arrive.
Here we go.
FC=0, but the Combined shows 18.
My PH is so low that it doesn't even match on the colors. More of a light yellow I so would say it must be in the 6.8 range (a guess)
And when I followed the instructions to test the TA, (25 ml water, 2 drops of R-0007 swirled) 5 drops r-0008 where the same "Should turn green" it stays red. Yes I re read everything and re tested. So I am not even putting R-009 in...because it is already red.
So I did the WHEN HIGH TA IS ANTICIPATED and used 10 ML sample, 1 drop R-0007, 3 drops R-0008 and it also stayed red...so didn't need tthe R-0009 to turn it red...it already matched 8.0 on the PH color chart.
Seems like this water is WAY out of wack...
Looking at the Pool Math Calculator it looks like a LOT of Borax to bring the PH up...40 pounds or so. 2 quarts 3 cups of 8.25% bleach to bring up the FC.
But what about the PH? I don't even know where to begin since I can't complete the test.
Sorry if this is newbie questioning...because, well, it is.
