I have a standard 20 gal. FW tank with a single fluorescent bulb. I can't recall what kind of bulb I have in there now, but it took going through several before I found one that seemed to stimulate plant growth as well as brighten up the tank. I did try to go by what was printed on the packaging, but one bulb that I got said it was "best for plants," but not only did my plants suck, but the light was too "blue" which made the tank dark and unnatural looking [in my opinion].
- For fluorescent bulbs, what's the best light spectrum, etc. to look for? Also, I read that there's something in the numbers that also indicates how DEEP the light rays will penetrate, but when I look at the labeling of the on-shelf lights, I can'd find this.
- What about LED lights? Are they better or same as fluorescent?
