I've got tons of microbubbles rising off the sandbed and on the rocks. The only thing I can think of is the fact that I just upgreded to 2x250W MH
lighting from 2x65W PC
. I've been running them for about 1 1/2 hours in the morning and another 1 1/2 hours in the evening, increasing each cycle 15 minutes each day to acclimate. Between lighting periods, the bubbles appear to subside. The tank temperature does rise a bit during the period as well, to ~83 F, but no higher. There is no cyano
in the tank either.
What in the world is going on? And, should I be concerned or is this a common thing?
