[chuggy]

I had a couple of questions im looking to retrofit my nano lights i was wondering if anyone new the shortest t5 bulb available?

Also im setting up a new frag tank i have a 175 watt mogul pendant with a lmh-120-175 aro ballast i was wondering what the best bulb for growth in a frag tank would be or what are your guys opinions on frag tank lighting

I believe the shortest t5 bulbs readily available are 24" but I know one company (Current USA) has a fixture (Nova) that uses 18" bulbs.

For a 175watt bulb, the best one is the Iwasaki 14k, according to Sanjay. I can vouch for this bulb as I used 2 over my 50. I had crazy growth but I wasn't crazy about the color (pure white).

i was afraid the max growth color was going to be whiter can i compromise and get a little blue with decent growth
