Started my 14g rimless biocube 6 days ago with 16lbs of live sand and some liverock from a friends tank.
Ph has been 8.0 for the last five days with hk going from about 120-160 over the 6 days and ammonia climbing from 0, to .25, to .50, to 1.0, to 1.25, to now back down to 1.0 or just under. I did start seeing the slightest hint of nitrites today, so I'm assuming the ammonia has spiked and started turning, but shouldn't it have gone higher? Also my ph dropped to about 7.8, why would that be?
