Thought I had the pool info in my sig, I guess it was just in the "about me". It's moved now. Latest result from the app below. I recently upped my SWG to bring my FC up a bit, especially with the dog in there. Can't seem to get TA to lower. I've tried bringing the PH down and aerating but didn't seem to move the TA much. It's new plaster so I'm constantly battling PH. I am hoping TA will lower over time as I keep adding acid to keep the PH in check. I'm sure the TA is contributing somewhat to my PH rise.No color change huh? Hopefully that's a good sign. Still, make sure to update y our signature with all of your pool and equipment info. You can also post a full set of water test results with your TF-100 or Taylor K-2006C test kit just so we can confirm that everything should be fine in regards to the heater. Perhaps the discoloration was related to the yard work.
