Neighbor with Yellow water after adding acid

[BigDave]

6 Gallons of 31.5%?!! Like a hundred pounds of Borax. half that for 15.7% YIKES! Hurry! There will be no liner left. Don't really know - Very complex to calculate pH.

[DougM]

Is the liner at risk?

[DougM]

Oh - and yes, it was 31.5%. I ran over with my 4 boxes of spare Arm and Hammer washing soda and got them in (12lbs) and he's off to walmart for a crap-ton of borax.

[Watermom]

Oh yeah his liner is at risk. Looks like this is his project for the day. It's gonna take a lot of Borax. Why on Earth did he add so much acid?

[DougM]

Its what the pool store told him.... he's got 12 lbs of my stuff and 20 lbs borax in. He needs to find more as he cleared out walmart.

[PoolDoc]

Tell him to buy "Washing soda" if he can't find borax. But, be careful. Washing soda will raise the pH more than borax. So he should be adding 2 boxes of washing soda or 4 boxes of borax via the skimmer, waiting 30 minutes to an hour; testing and then repeating if he sees no change in pH. Once he sees the SLIGHTEST increase in pH, he needs to drop back to 1 box of washing soda or 2 boxes of borax . . . OR he will overshoot and end up with high pH.

Its what the pool store told him

Probably from a computer print out because the TA was high. THIS is a reason I do not like computerized pool store testing (and I have done my share of it and crossed out their print out instructions and wrote what they were REALLY supposed to do.)

Hope Doug is UPHILL from his neighbor.....
