How to insulate a crab tank better?

[HermitGuy3]

Hello! So in my "what temperature should I set my heat pad to?" thread I was asking what temp I should set my heat pad to, and I set my pad pretty high. However, it seems like it is doing little to help, and I don't want my crabs to be cold. I was wondering what things I could use to insulate my tank better? Right now I have a blanket around my tank and partly over the lid. I have my mesh lid wrapped with plastic wrap 3/4 of the way, should I wrap it all the way? The blanket is not over the heater.

You can use a product like Reflectix. Or wrap cardboard with tinfoil. Or use something like one of those foil-looking things that go in a car windshield to block out the sun.

I would also wrap the majority of the lid with plastic wrap, will help retain heat and humidity (think like a greenhouse).

Would I put this insulation around the outside of the tank or on top?

You can do both.
