Hi Guy, Can anyone tell me if this is algae issue.. tank is 150 gallon with 40g breeder as a sump, and has been up for 6 months. I used I/O salt, going to be changing to I/O reef crystals next water change. Water is 79 degrees , salinity 1.024. I recently added the galaxyhydro 300 watt led x 2... blues are on for 10hrs per day and whites for 8 hrs. I would have the blues come on first for an hour and they would be last to go off (1hr). I current do no have my reef octopus xp2000 slimmer running bc my sump isn't baffled and it does not dial in properly due to evaporation. I do only have a few small damsels and 2 green chromis. I have included a picture of the "algae" and my results from my water testing ...
Is this just part of my cycling or a late bloom of some sort?
