OK, thanks for your help with this. Intended to target 50 for TA, but brain misfired and I wound up around 80. I will try it there with a pH of 7.6 and see how it creeps up. I'm interested in the borates for water feel too, but will delay that to see if I can get pH and TA to play better...

Thanks, that is a helpful thread that I had seen but couldn't find again. It is geared towards pools, so if using a hot tub do I also need to do the borax/acid in batches or can I just go for it? PoolMath says I need 353g borax and 175 mL of muriatic acid. As for why: I want to avoid raising TA...

Hi folks, My local community (Ottawa, Canada) has tap water with a high pH (9.39) and low TA (35.3) (per city reports). The tap pH is too high to measure, but the TA checks out with my Taylor test kit. My problem is that if I use Muriatic Acid to drop pH to around 7.6 and add Spa Up to raise...

Want to be taking a scientific approach to water maintenance within my knowledge base. I am using a 3-part bromine chemistry. Part 1 is 35% sodium bromide (liquid). For part 2 I was using Potassium MPS, but the powder available here is weak (32%), and I realized I could be using cheap bleach to...
