I have a 20,000 gallon negative edge pool that is low on TA (~60) and taking daily acid. I figured this would be an ideal situation to begin borates. I dumped in the whole 55 lb can of boric acid obtained via Duda. Beginning pH was 7.4 and it did not change after the addition. Resulting borate level was 30 ppm per the LaMotte test strip. FC is 3 ppm and I'm using the Triclor tabs to chlorinate until my non-existent CYA levels are built up. I'll then switch to liquid chlorine. Visually the pool is the same, haven't gone swimming in it yet to test the "feel." I'm hoping the borate addition may also help reduce the honey bees that plague me every year. I also must say that the 55 lb boric acid bucket, now empty, makes a very nice trash can. I'm wondering if I should order another bucket and increase my borates to 50 ppm.
