whats the smallest size tank they can go in? cause the ones that can go all over the tanks look buy i only have small tanks
I have a single led in my 20g and a 4" cold cathode in my 18G
both are effectivly illuminated.
I would say that most of these kits come with two 10" tubes but you don't have to run both
In my 62 I run 1x 10" tube, that way i have a spare tube for when it goes in around 9000hrs time.
