michael.qian Posted May 6, 2007 Report Share Posted May 6, 2007 Hi all I have a 140 Litre tank, with 36W lighting by 2X Arcadia Freshwater Bulbs, each 18W. It looks really bright, but is this considered high, medium or low? This will help me decide what plants I can add. Thanks Quote Link to comment Share on other sites More sharing options...
evilknieval69 Posted May 6, 2007 Report Share Posted May 6, 2007 That would be considered low.... 1 watt per litre is a good start, but is not always the best way to go..... 100W's on a tank that size would be moderate lighting, and could keep pretty much any plant you want..... 36w's isn't going to keep much looking nice Quote Link to comment Share on other sites More sharing options...
