Received my TF-100 kit today. Tested this evening prior to adjusting anything:
1. FC: 2.5 (was 12 this AM, but just added the CYA this PM after sampling)
2. pH: 7.2
3. TA: 50
4. CH: 60
I added bleach to drive FC back up to the 12 to 15 range as I wait for the CYA to dissolve. Will be checking FC twice daily to keep it where it needs to be (hopefully).
I added 49 oz (by volume) of CYA (targeting 70 initially - have a SWG) - I split it more or less equally between two nylon knee-highs, tied off to the pool frame/wall, and submerged about a foot below the waterline.
I added borax to bring pH up to 7.6, but may have overshot a bit (maybe to 7.8 or so) as I just realized I had the wrong TA value entered (calculator was set to 80 rather than my measured 50). I added 16 oz (by volume) of 20 mule team borax.
I will measure/test CC after I run a OCLT tomorrow night.
Water is very clear, with minor precipitates. Wad of white paper towel stuffed in the skimmer for 12 hours is still white and there is no staying, etc. Pump pressure is still right about nominal at the initial set-up. I plan on putting in some DE over the weekend.
So it appears my TA and CH are close to where they should be. I'll bring up my TA with some baking soda tomorrow. Should I be bringing up the CH? It's at the floor of the range for vinyl.
