First, I finished a SLAM a couple of weeks ago and the water looks better than it has in many years. My numbers are:
I needed a couple of parts from the pool store yesterday and thought I would have water tested for fun. Their numbers were pretty close to mine except TA (theirs was 44 w/stabilizer correction). The wanted to sell me alkalinity, calcium hardness increaser and cyanuric acid. My CYA has been at 30 for most of the time but a lot of rain has lowered it so started bringing it up again. Also, my pH has been rising a bit and I keep lowering it.
My question is: is there anything I need to do to keep my water looking this great?
