Hokay I'm tired of this. I have 3 Zoo Med uth's on my 10 gallon tank (size small, for 10-20gal) and the hottest area according to my new zappy temp gun is 85 F.

I can't upload photos from my camera right now, so I've drawn a rather horrible picture of my tank and uths:



This is kind of viewing from top down. The two red bars on the sides are uth's on the sides of the tank. The red bar inside the gray area is underneath the tank. The drawing isn't exactly proportionate, but it gets the idea accross.

I have tin foil taped to half the underside of the tank to disperse the heat (or lack thereforeof) on the bottom. There's about 1 to 1.5 inches of aspen snake bedding... and I think that's all the relevent setup details(?)

Even if one or more of my heaters have stopped working, I was having problems long before now. I'm thinking I need larger uth's, and I want to use a different brand. Correct me if I'm wrong, but I shouldn't need 3 heaters to keep a 10 gallon tank the temps they should be. I'm shooting for 90-5 F on the left side of the tank, and 80 F on the right. The right side is fine actually. Its staying at 80 F like a good tank. Also, I have a Zilla temperature controller for the hot side, which I have set for 95 F. The Zilla controller is on almost constantly, the instructions indicate I need larger heaters when that happens.

So my main questions are.. do I need larger heaters even though I have the right sizes according to the Zoo Med instructions? And can anyone recommend a different brand of uth?

Thank you!
