JW if a 10g would make it too difficult to keep SPS and if it would be better to have a micro skimmer on it which tend not to work or if I should just do weekly waterchanges of 25%? I plan to make the tank rimless and get a PAR38 Bulb or similar to hang above it. A small powerhead as well as a HOB powerfilter with polyfiber to get some crud out. Or maybe put cheato in it.
