Heh, except I just added a DIY version of the undergravel filter using perforated PVC pipes, and the tank has never looked better. I also had 3-96W AHSupply lamps/reflectors over my 90 and it was just too much work. Plus the heat was a problem. Much better with two lamps, which is about 2 WPG. So the rule of thumb does still work for certain tank sizes. I'm anti-carpet plant though, so it's just IMO.quote:
I want to add that the old "guideline" for determining appropriate lighting level, i.e., watts/gallon be heaped into the trashheap of past aquarium keeping, at least for planted tanks, much like the undergravel filter.
I currently have 6700K lamps and I'm thinking of trying the 8800K lamps. How did you like them?quote:
I have used 8800k, 6700k, 9325K and a real learning experience with a 50/50 bulb that came with my first light kit.
