I recently bought a house that came with an IG Pool and a Hot Tub. They were part of the big sell, but now I'm realizing how much work they are! Since we had no clue what to do, we went to the local pool store and followed their directions. I already posted in another section about my pool, so I'll post my hot tub info here. I've been reading many of the posts on this site including all of the stickies, Pool School, How to Chlorinate lessons etc. So, I'm at least familiar with what I should be doing. Sort of.
Every day I test the chlorine levels (I chose chlorine instead of bromine because I thought it would be better for going back and forth between the pool and hot tub) and every day they go back to zero, or close to it. So, I usually double the normal dose of chlorine to get it up to around 8-10ppm. Until now, I was only using test strips. I just bought the TF-100 test kit and ran the full gamut of tests today for the first time. Here are my results today without adding any chlorine yet:
pH - 7.5
TA - 100
FC - 0.5
CC - 2.5
TC - 3ppm
CYA - 65
I'm not sure why there is so much CC, since I add so much chlorine every day (essentially shocking it? I think) It's also very cloudy right now (heavy use the other night during our Labor Day/Housewarming party, minimal use any other day). Before today it was never cloudy.
The hot tub is about 8 years old and a lot of the jets don't seem to work. Either that, or I don't know how they work. I turn them, but they don't seem to do anything. There are some dials on the top that can be turned on, but they're all loose (probably broken) and only one of them actually works. I may look into buying a brand new hot tub in a couple years.
Thanks for any help!
