I have a 75 gallon tank. Started about 5 weeks ago. I have used only RO
water. I have 80 lbs. of cured LR
in tank. My ammonia, nitrate, ph
and nitrite are all O. I am using 2-301 powerheads for circulation and getting some circulation from my magnum 350 and also my protein skimmer. My lights are 2-10,000 CF
55 watt each and 2-actinic 55 watt CF
on the tank 12 hours a day. My salinity 1.022 and my water temp is 78 degrees F.
My question is I am seeing some green algae on my LR
and crush coral. Some on the glass also and I have some fish in QT
that are about ready to be put in the tank. Is this just a phase my tank is going thru or should I be concerned. I have not done any water changes, should I? What about crabs or something else to help with maintenance? This is a mostly fish set up but I would like some corals. Please help.
