I'm also currently in the process of my least favorite part of crabbing. Heat! Are there any blue owners out there that can tell me what temp they prefer? My issue seems to be that with the ultratherm and just UVB light I can keep the tank at 79.7 at substrate but it's high 80's up top and mid 80's in the middle. Is that too cold at substrate level? If I use CFL's with the UVB it gets really hot up top like high 90's. Substrate about 81. Then at night if I use 2 15 watt moon glow bulbs it's 80-81 at substrate and high 80's up top. So it's a bit warmer at night! If I use 1 15 watt moon glow bulb the substrate level is 79 and mid 80's up top. I could try 1 25 watt and see what happens? I just hate that the bulb is more to one side of the tank than the other but the hood is set up to run 2 bulbs on each side. Any thoughts?
THANKS!
