Was starting to stress fighting my hot tub water issues. Mainly PH rise. The PH down, aerate technique to beat down the TA really saved the day! Used a little 20 mule team borax and got the PH at 7.6 I haven’t had to adjust anything for 3 days and counting. A new record for me. The water looks good, feels good, doesn’t smell. I think it’s fixed! Only thing is my TDS is getting up there at about 1200 ppm from all the mistakes I was making in the beginning. I hope I can get it right again after I dump the water before long. I’m not so trusting of asking the pool stores for help either. I already have a shelf full of chemicals. I don’t need anymore. I got a Taylor test kit. Wow. The test strips should be illegal. Sooo misleading and vague! I wanted to iron this out myself. Reading thru a lot of theses conversations I’ve picked up a lot without having to poke anyone personally. So, there’s a lot of smart, experienced people here I’d like to say thanks so much for sharing your tips and tricks! Ed.
