You won't be losing light...? I have several of the fixtures. While they're probably more expensive than you need for this project (they're not my favorite fixtures - but they're convenient), you definitely wouldn't be losing any light because there are a few extra blue LEDs attached. If you don't want to use them, don't flip the blue switch on.
i have a 30in t5no on my 20l. i have to admit for plants its the best growing tank of my 6. i just borrowed a PAR meter yesterday and plan on doing some testing with it today. anyway. i know t5 is not as flashy and awesome sounding as LED but don't count it out yet.
Randy, I've had the light for about 2 months now. I did have some algae in the beginning while the plants were getting situated, but no algae problems anymore (but it could be because I have lots of ramshorns...but I purposely want lots for when I get pea puffers).
Hi, Fr0sty, how long have you had that light on the tank? Any issue with algae? I'm thinking to get some for my 20G/Ls, but not sure to get FugeRay or the DS II. (for 24" long ones, only 5 w difference)
