I have a fluval t5ho quad fixture. Was gonna do a high tech tank but decided not to spend the money on another co2 setup. I got mine for $230 plus shipping online last february. It's still brand new inside the box. I have an ad up on Craigslist for $180 but I'll go lower for members here on this forum at $150. Sorry, bulbs have been sold a while back. If you want to be able to test it, gotta bring bulbs, 24w. Regular t5's will work too.
