Michael here, from hot and sunny (though not last night) Las Vegas, Nevada! My wife and I just bought our first house and by default inherited the above ground spa that was here. It's made by LA Spas and we've no idea on the exact volume. We estimate about 400 gal. based on the dimensions of 8.5' x 7.5' x 3'.
Also by default we inherited the previous owners bucket of chemicals and test kit. Pretty much everything we needed, but I went and bought a Taylor K-2006C so I can keep track of the CYA and CH. We're known for incredibly hard water here in Vegas, in the top 2% of the U.S. (mine tested at 17 gpg.) So when tested yesterday our CH came in at 275.
I'm pretty comfortable with reagents and testing as I had a strong chemistry foundation in H.S and College, so I want to be an expert in this eventually.
We did a fresh fill about 10 days ago and I've been pretty good at getting the TA between 80-100 on a regular basis along with testing the pH between 7.2 and 7.8 I add pH+ or pH- to get the pH to 7.4-7.6.
i look forward to learning as much as I can here! Thanks everyone for assisting me in my journey!
