So about 6 weeks ago it started and at first I thought it was diatoms. No big deal, right? Toss in phosphate/silicate remover and black out a few days, looks great! And boom there they are again.
I've been vacuuming the sand through a filter sock and dumping the water back in as to not feed it with any new nutrients. I ordered some MB7 and biofuel and am expecting it this Friday. Currently I have a blanket over the tank without any lights running for the day to keep it under control. I've also reduced feeding.
I use rodi water and do 10-15% water changes every other weekend.
I'm running a skimmer, and I have a uniquarium with a built-in fuge w/ chaeto and LR.
I attached a couple of photos, too.
