2015年5月15日 · When boric acid is added to water, it mostly remains as boric acid and only some of it dissociates to lower the pH and become borate ion. Adding 50 ppm to water with a pH of 7.5 and initial TA of 80 ppm will lower the pH to 7.3 so even adding enough boric acid to increase borates to their maximum recommended amount doesn't lower pH very much.

2015年7月11日 · Be careful to check any form of boric acid powder that is not sold specifically as boric acid. Make sure it is 99.9% granular boric acid with no additives. Many products that advertise as boric acid are typically sold as insect control products. They will often be a mixture of boric acid and other ingredients like diatomaceous earth.

2018年8月14日 · The boric acid I used 35 pounds and am using the test strips for that and after two test strips it looks closer to the 80ppm than the 50ppm. What am I doing wrong? FC is currently real high at 12 since I am dialing in the SWGG - ran it for 24 hours at 50% - now I'm running it at 10 hours at 50%.

2020年4月26日 · I got a 42,000 gallon pool. Pool math says that 70lbs of boric acid should yield a ppm of borates of 35. I ordered 70 lbs of boric acid granular form from duda energy. First of, does adding 70 lbs seem about right for my pool? Second, should I try to lower the TA a bit before I …

2022年6月27日 · Boric Acid: powdered sugar: water Boric Acid: powdered sugar What about BORAX as opposed to Boric Acid? Would you use the same ratios (Boric Acid is weaker than Borax, correct?) I can use my mortar & pestle to make the Borax into a finer powder if I use the dry mixture, but with the liquid version it seemed to break down fine.)

2010年6月2日 · If you are adding borates with borax and acid, they will probably throw off the PH for a few hours. It is best to give the borax and acid four hours to mix without swimming and then double check the PH before getting in. If you are adding borates with boric acid, you only need to wait about 15 minutes before swimming.

2017年6月6日 · Boric acid is very fast to dissolve. I just added 10-lbs to my pool today to bump up my borates (5 scoops from an orange DE scoop weighs about 2 lbs when full of boric acid). All you have to do is add it in stages (maybe 10 to 15 lbs at a time) and then brush it around vigorously with your wall brush. It will dissolve very rapidly.

2012年6月28日 · I just finished the procedure for getting rid of mustard algae. Everything went great, though there were some stains (or something) on the bottom of the pool in spots that would not get clean. They were in the deep end, so I couldn't easily get to them to scrub them by hand, only with the pool...

2020年11月21日 · My pH kept rising which is why I tried the boric acid, and it's actually been stable since. My pH is 7.6, bromine at 2-3ppm, 50 Alkalinity, calcium ~225. The water looks perfect, but when I turn on the Air Control Valves (adds air to jets), bubbles start forming and combining into foam.
