So I removed the Chemi-Pure Blue this past Saturday after a water change, and after 48 hours, the phosphate went up to .23 (using Hanna Phosphate Checker). Coincidentally, I noticed the algae fuzz on the sandbed has improved. The challenge is how to get it down a bit without going back to the chemical filtration.
dKH also dropped .06 in two days.
Going to continue to monitor both. If dKH is indeed dropping .03 per day, and increasing to X after a small water change, that should give me a starting point on how much to dose. Is there a dKH calculator out there?
