thought id post some pics of my 40 L reef nano, its an all in one aquamedic nanowave 9, has 1 x 24w white pc light, 1 x 24w actinic and 3 LED night lights, has a cool mini skimmer built in the back and a fuge area with its own light. Had hubby put 2 pc fans in the hood to combat over heating issues, and added a hydor koralia 900l/h pump for extra circulation. Been running for about 9-10 weeks and havent had too many algae issues, i do 2 x weekly NSW water changes and i think its what has helped.
