oh yeah just read your older post...the WPG rule doesnt really apply to tanks that small... its kind of like the inch of fish per gallon rule....its just a suggestion
perhaps have to seperate sub forums in your planted/refugium section one for fresh planted, and one for salt planted/refugiums. perhaps even a brackish planted? I understand this is a salt nano site(forum content much better than nano-reef imo by the way) but its would be nice for the members...
