I guess I haven't been on in over a year.... shame on me. it is definitely Acanthastrea echinata. I haven't been able to do a whole lot with my tank in the past year due to a down turn in the industry I work in. It is on the rise however and i am starting to get the saltwater bug again.
Can anyone help me identify the algae I'm dealing with?
I haven't checked my parameters in a really long time but I do weekly 5 gallon water changes with RO/DI water. Zero TDS according to my meter.
