AMorgan,
I’ve been here for a few years and have found this forum to be AMAZING. But it’s a lot of info at first to absorb. Here is what has helped me:
Do not listen to neighbors, Facebook, pool store, or anyone else UNLESS THEY FOLLOW THE TFP METHOD. Just nod and smile at those people but IGNORE them. Once your pool is perfect and you have a truly trouble free pool feel free to work on converting those people.
Buy and use the test kits that are recommended here. Do not take your water in to the pool store for testing.
Only use regular bleach or liquid chlorine. (Same thing just different strengths). No tabs or fancy bleach. I just switched to a SWG, but I used to buy gallon jugs of liquid chlorine from pinch a penny because my local grocery doesn’t keep a lot of the regular Clorox on the shelves. Bleach has an expiration date so once you are done with your current SLAM only buy what you will use in a month or so. Wear old clothes when you deal with bleach or be very careful not to splash your clothes.
I have high TA in my fill water and my ph drifts up so I keep muriatic acid on hand to lower TA and Ph. Stay upwind or hold your breath when you add it to the pool, the fumes are horrible.
I keep CYA on hand because I have a lot of rain here in the summer which overflows the pool water and eventually dilutes the CYA level.
Download the pool math app, it’s a great thing to keep track of your pool. Plus it figures all your chemical additions and logs them.
Good luck! Crystal clear, sparkling water is in your future if you follow the pool school advice and the experts here.
