I just moved my Enchi girl up to a 40G breeder tank from a 20G, to make room for my new Pewter boy.
Both tanks have a UTH on a thermostat. I have a CHE hanging above the 20G and decided to go with a red lamp on a dimmer to help heat the 40G.
This seems like it is working ok. Being on a dimmer I can adjust the level and I can see what's going on when it gets dark.
I am thinking of changing the CHE to a red light on the 20G.
I mentioned using red lights on a facebook group and a couple said to get rid of the lights.
The only issue I can think of is humidity. The majority of the screen tops is covered with lexan. I am using cypress mulch.
Any reason other than maybe trouble with humidity to not use these lights?
