akdylpickles Posted August 6, 2014 Share Posted August 6, 2014 I have a 10 gallon with a 20in 4 bulb T5 HO fixture. with 2 10k and 2 actinic. Is that enough light to grow most sps? Also are there any other 18in bulb choices? I can only find 10k and actinics Link to comment
Chadf Posted August 7, 2014 Share Posted August 7, 2014 Bulb choices are pretty limited under 24". Give a couple frags a try though, it should be fine. Link to comment
bdevillier19 Posted August 7, 2014 Share Posted August 7, 2014 I used a 4*18w t5 over a 10 gallon and was able to keep pretty much anything (no clam). Even had 7 RBTA in there at one point. Link to comment
