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:
/NH2 ---- .25ppm (down from 5- 7 ppm
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
most likely the fueel source at this stage of the cycle?
Thanks for the help.
