Day 21 @ 1000
pH 7.2
FC 3
CC 0.5
TA 80
CH 250 (I think it has been 250 not 300)
CYA 30 (as tested yesterday)
h2o temp 52
I'll looking at a CSI of -0.67. If I raise the pH to 7.5 either through aeration or Borax to 7.5, I am still looking at -0.37. So:
1. Should I raise TA back up to 90? - No
2. Leave CH at 250? - Yes
3. Use aeration for natural pH rise? - No, let it rise naturally to 7.8
4. Use Borax to raise pH to 7.6, and leave TA and CH alone? - No
