Correct heating method

Yeah, a proper sized Ultratherm for your tank would be between 23 and 46 watts, by comparison.

Thanks. I'll return these and get a bigger one. Then is the only way to make one side warmer is to use a lamp which of course zaps the humidity?

A UTH will create a gradient front to back, rather than side to side.

OHHHHHH. Lol. Gee.

When I setup my 2 tanks I put my heaters on the bottom to one side. My crabs are small so the substrate is around 4 to 5 inches deep. I put the small pieces that came with the heaters on the corners of the tanks and was careful not to place the plastic part of heater that attaches to to pad where a lot of weight would be on it. Both tanks are on a stand that I can put my hand under to check it to make sure it is on and warm.
My main problem seems to be that the sand is drying out. I mist both takes well at least every 2 days if not every night. I have removed the shells, dishes, and toys and misted and mixed up the sand/cocofiber mix and moved it around so get it moist again. I've only had to use my heating lamps now that the weather is cooler, which the sand is drying out more. I do my best to be gentle as not to disturb the ones that could be molting.(I check the tanks to see who are up and about the night before I mix up the sand.) MY QUESTION: is there a simpler way to keep the sand from drying out too much?? They seem to be doing well, I just don't want any to start digging and get smothered from dry substrate. Any suggestions?

Oh.... That is exactly what I did. They can not be placed under the tank. I placed my heaters on the back of the tank, just above the substrate. It is safe, and no more dried out sub.
