It looks good. I am a big fan of blue damsels though a bit mean their blue over white sand realy stands out.
I think your using a skilter filter ? .
They actually arent bad for smaller salt tanks the skimmer does work once you adjust it right and its extra water movement .
I had one on my first 30 gallon marine tank but it just put to many bubbles into the tank which wasnt good for the fish,etc . So got a CPR backpack.
if the company would fix that problem they would sell more. Do you have that problem?
