Sylvania Gro-Lux bulbs - any good?
I've been reading this site for a couple of weeks now, and decided a planted tank might be in my future. I've been in the aquarium hobby for about 15 years, and never did a planted tank.
I have a couple of 20H tanks that I'm considering on using for this planted tank project. My question is, has anyone used the Sylvania Gro-Lux bulbs? and if so how would you rate them?
I plan on putting 4 of these over one tank, for a total of 80 watts of light.
Thanks for any input you can give.
