How many VHO tubes do I need for 55 gallon

MH...very true. I've been thinking alot about them. I was thinking mh with T5s. :rolleyes:

Clam,
I've got nothing but good things to say about overdriving the bulbs with an IC660 and running T5's. I followed along with Moonpod on RC...he use to have T5s only on his 180. Then switched to MH because of slow growth..not color. His were running for almost 2yrs before I got into them almost a year ago.
