How important is that the UVB bulb is 2/3s the length of the tank? I'm going to have the 12" t8s on my 4x2x2s for a bit and am wondering how much I should prioritize upgrading them
#UVB light length
muted plover
livid kayak
i have a 12 inch uvb on my 4x2 temporarily until i can find a 6% of the size i need so id say its fine to have a smaller uvb for now but id more be concerned about a t8 not giving proper uvb on an enclosure of that height
