One of my friends has had his 55g fowlr
tank running for 3 mos now. Has 10g sump with 400gph pump, 5lbs of rubble and 60 lbs lr
in the tank. He has 2 45w 10000k t5ho lighting, 2 300gph powerheads, eggcrate hood. His params are 0 amm,0 trite,20 trate, don't know the phosphate.
He called and asked me to look at something pink on the sand and I sucked some out with a hose and the sand was clumped together.
I am assuming this is cyano
because it had the color and somewhat of the feel. It is in this one 5in section only(we searched the tank)
He is lite on cash and I want to help but don't really know how on a budget.
He does 20g weekly changes with ro
water an Instant Ocean salt mix.
Do you guys have any help?
