So I'm about three weeks into my cycle and noticed 3-4 of theses growing on my rock.
So are they a good sign? and what are they? It's a 29 gal
with about 25lbs of live rock. No creatures yet just waiting for the cycle to end.
Last test 2/9: PH 8.2 - Ammonia .15 - Nitrite .1 - Nitrate 25 - Spec Grav 1.025 - temp was 77.5 I'll do another round of tests tomorrow.
