Setting up my 20 gal innovative marine tank if anyone has any imput on things that I can do differently or better or if it looks good for a new mini reef any help would be great I'm used to setting up much larger tanks and it's been a couple years but I wanted back in the hobby pics to come currently running mp10 refugium on the back bio balls in the chambers and couple pieces of rock just on the first week of cycle
