I'm new to reef to reef and I'm looking for a good forum with good topics and not a lot of ads. I hope this is the right place.
I have a built in 90 gallon bow front with a 30 gal. refugium sump. My tank has been up for about 6 months.
Can anyone tell me what this is. At first I thought it was a polup, then it started moving. Is it good or bad?
