I know that ph can swing during the day, but how about Alkalinity?
It seems I've dropped from 3.0 (8.4dkh) to 2.0 (5.6dkh) in abouta month ( I tested this morning before lights came on). The ph seems stable and the Ca has dropped from 600 to 560 in the same month. I know this is high anyway - I assume it was a result of the 120 lbs of aragonite I put in the tank (the tank is only about 3 months old).
Beside weekly water changes (about 2 gal), good filtration (see below) and the addition of baking soda in the water changes, what else can I do to maintain the Alkalinity? is this rate of decrease normal?
