So I have this weird brown algae that keeps showing up on my new rock..frag rack..frag plugs..and powerheads. No where else. It doesn't grow on any established rock either. It's a weird spore like algae unlike I've seen before. I clean my my40s and 2 weeks later it's back again.
Frag rack in front of tank midway up. I check on them every day or so and .are sure polyps start coming out. I leave them on rack for a few weeks, then I glue frag plug on to rockwork and leave alone
I've used reef crystals forever. I know a lot of reefers with beautiful setups that only use IO with success. You can use any just make sure to stick with it and don't constantly change
