Hi all: Me again with some questions.
55gal with about 75lbs of LR/Base/Reef rock. about 920 gph of flow going on with 620 of that coming from powerheads.
Mid cycle (fishless) readings:
NH3/NH2 ---- .25ppm (down from 5- 7 ppm)
NO2 ---- .8ppm
NO3 ---- 50ppm
It looks like I have a cyano outbreak going on. Algae on the glass, some of the equipment, and rocks. I am thinking cyano b/c the cyano on the rock is producing bubbles and I understand this is typical of thriving cyano.
Is it time to do my after cycle water change to dump the NO3?
How much of a water change should I do?
Should this eliminate the NO3 fuel source for the cyano?
Is NO3 most likely the fueel source at this stage of the cycle?
Any ideas?
Thanks for the help.
