New, Need help with small tank setup

[Grim8899]

I use black lights in both my set ups and they keep the tanks a little less hot than reg day bulbs do NAND there the same watts,a few degrees difference,maybe 2-3

You apparently didn't do much partying as a teen..black lights are purple

Black lights and the heat light are two different bulbs.
BTW welcome back and good bye
