I'm pretty confident the plugs are tight because I had both out when I used pressure and vacuum gauges to get readings for calculating total head. It was fun to do, but I had estimated 70 feet of head and sure enough, it was 70 on high. I was more interested in the head on low so I could...

Thank you Matt. One last thing I forgot to mention... I noticed for several months now that I see a lot of bubbles through the clear pump lid. The overall air bubble on high is pretty small, maybe 2.5 to 3 inches in diameter in the dome. The bubbles appear regardless of suction source (pool...

Thank you Matt, Given your enlightening math explanation, maybe going up from 40 to 50-55 ppm borates could further slow the rise? What do you think? If overall acid usage is truly the same, then what do I have to lose? There's definitely no cracks in my plaster and it is nice and smooth...

Hi Matt, 1. pH was at 7.6 immediately before adding borates. TA was at 70. After adding borates pH was 7.6 and TA was at 90. 2. Fill water pH=7.6, TA=70, and CH=120. 3. Plaster is ~15 months old and in excellent condition, that is, white and smooth. 4. After filling with water, I brushed...

I sure will Yeti. I'm mainly turning off the SWG to see how much of an impact it has on pH versus what is now an unknown ( 14 month old plaster?). I haven't turned it off yet, but I will tomorrow morning before the pump kicks on. I will check and adjust my pH to 7.7 at the same time and see...

So Yeti and Naples are in the same situation as me. I'm not sure how new your pools are, but mine is 14 months old now. I'd think the plaster is done curing. My SWG is only running at 30% for 8 hours on low speed, so it's not like it's generating that long. It's keeping Chlorine at 4-5 ppm...

Thank you both for your responses. For camueller, I do know how to lower TA and replacing water isn't it. Sorry if it sounded that way. Also, wow, I thought my fill water TA was a bit high!!! Out of curiosity, how long did it take you to get to a TA of 70? However, you and JoyfulNoise both...

OK, months later... Now I really have a "problem" I can't figure out. I added borates, but the results are less than desirable and I really hope someone can solve this. First let me give my chemistry before adding borates. pH 7.6, TA 70, CA 80, Salt 3200, CH 325, FC 4 CC 0. A note on TA...

Thanks so much. I was following the recommendations for TA on the Pool Calculator with the Trouble Free Pool setting, which suggest TA = 60-80. I checked last night and it is at 80, so I'll push pH down to 7.2 and aerate with the water fall to drop TA to at least 60. I like the idea of rarely...

Hello all... new to forum and this is my first post. I have read all that I can find regarding adding borate to a pool and am considering adding to my pool, but would like an answer to some questions first. I have an ~15,500 gallon pool (about 5 months old) with a SWG. My CYA is at 40, TA is...
