I am in the process of switching to the TFP method. I've been using a local guy to maintain the pool, since I bought the house in Sept 2015, and I've watched him throw tabs in a floater and dump bags of shock periodically, and never test the water. Decided it is time for me to takeover.
Had a heavy rain over the weekend and the pool is cloudy. Did my first test today. I think these are the results needed:
CYA: 70 (I did it twice and got about 65 both times, but no line for 65, so not sure whether to round up or down to nearest mark)
After having tabs as the primary source of chlorine, expected the CYA to be higher.
Looking at the chemistry info, looks like I need to get FC up and CH down. Will follow the steps in the pool chemistry and pool math.
Any thoughts on the CYA, should I work to get that down as well, or is it close enough to being ok, for now?
Since I'm just starting out at this, any advice is greatly appreciated.
