Just kidding, I don't normally say howdy, and contrary to most beliefs, I don't even own a single pair of cowboy boots or a cowboy hat LOL! The fam and I just moved into a house that has a 10 year old gunite/plaster pool. It was previously a salt water pool, but I haven't added any salt, due to the how highly corrosive it can be. Since doing a little bit of research on here, I don't think I need to convert the system over to a chlorinator, since it appears I can just add all necessary chemicals directly into the pool. I just bought a TF-100 test kit, so I'm very curious to see where all of my levels are. Anyways, I'm sure you will hear from me again, because I'm sure my levels are highly out of whack! Take care!
