Stupid question maybe. Can I use the pool math calculator to determine amounts of MA for my hot tub, or is just for pools? I have a hot springs spa that I want to start using the TFP method on. My bromine is always good but my ph and TA are always out of whack and I want to start addressing it since I bought the test kit and I have been working on the new pool. I use bromine tabs with the spa time shock but I have not been shocking it regularly, that is changing as of today! My husband primarily uses the hot tub, I get in occasionally. We rarely have guests in it but always shock after heavy loads. We replace the water about every 3-4 months and use granules after refill. My question has to do with how much MA to put in to lower the ph and TA.
I just used the last of the shock, so my bromine is at 10. Here are the rest of the numbers. My HT is 525 gallons.
PH 8.2
TA 140
CH 275
