Things seem to be going ok w/ my spa water. pH staying around 7.4-7.5, TA 100, calcium 130. Trying to get the dichlor right now.
I was putting 2 tsp each night when my wife and get out. I haven't been testing the water chlorine level 15 minutes and 2 hours later as suggested by the 'Northman style' - which I have decided to try. Anyway after putting 2 tsp in last night the chlorine was at 13ppm 15 minutes later. And 5ppm 2 hours later.
Tonight I only put 1 tsp in after we both got out. Chlorine was 5pp 15 minutes later and 2ppm 2 hrs later. I'm planning on trying this a few days to see if the chlorine stays about the same. Sound right?
