Hi:
It is JBJ 29 nano aquarium. It is a few years old but I purchased it last year. I am running an Aquamaxx HOB-1 skimmer using GFO & GAC. I recently treated the tank for Cyanobacteria which the few SPS corals didn't like at all. Also my zoa's have bleached a bit and some don't open fully yet.
I recently removed a toadstool leather coral that I thought was giving me issues.
Also I have some GSP that are close to a hammer coral.
Do people recommend vacuuming the sand bed when doing water changes? The few times I have done it I get a lot of debris out of it.
Thanks,
Michael
