The Great Tetraborate Experiment!

[ccr-n-ia]

17K AG pool
pH = 7.6 (consistent for 6 weeks since adding borax)
TA = 140
BOR = 80 (oops)
CYA = 5 (low on purpose)
using 6% bleach with a peristaltic pump feed to maintain 3-5 ppm CL


Question - my TA is gradually floating upwards (started out at 120, now at 140 - I have a heater, so want to drop it a bit).

Anyway, I'm prepared to lower the TA (and pH) using muriatic acid, but want to know if the strategy for reducing TA is the same as posted elsewhere on this forum - use aeration?

drop the pH to 7 nand aerate. Also, the test strips are hard to read above 30 ppm. Try doing a dilution 1 part pool water and 1 part distilled and testings and see what you get when you multiply the results by 2 then try 1 part pool water to 2 parts of distilled and multiply by three. If the dilutions confirm that your borates are high I wouldn't worry too much about it.
