The last couple of weeks, I've had a HUGE spike in phosphates. I have a 29 biocube, about 8 months old. I'd been holding steady (although high) at about 0.2. Nitrates had been holding around 30. I started dosing 1.5 mil (1/2 dosage recommendation) NOPOX last Monday, and the nitrates are down. The only change was I added a Hygger wavemaker 3 weeks ago, which stirred up my sand bed until I got it situated in a better position. At Aquashella, I visited with a couple of people who believe this was the cause of the spike. I do a weekly water change of about 4 gallons.
Today's readings, before my weekly water change:
KH - 7.5 (had been staying between 8 and 8.2 previously)
Ca - 450 (has remained stable)
NO3 - 25 (down from last week's testing of 50)
PO4 - 1.0
PH 8.2 (stable)
Mag - 1485
Suggestions?
