thanks mate, i actually just got another tank yesterday so i am on the look of the lights again. I am going to go search for some grow lights on ebay now, i think i have a grow light atm actually. it was a t5 fixture from bunnings with two 26w t5 bulbscyberhog05;4557744; said:Instead of doing an aquarium specific search do a grow light search. They are much cheaper than aquarium lights and are better IMO. I picked up an 8bulb t5 with plant specific bulbs for less than 200....shipped
