hot summer and heating problem

[crabs_lex]

i keep my hermit crab in my room (which is the best and only place for me to keep them) their temp is usually 75 and the lowest it’ll go is like 73 (which ik is low) but it is just so hot in my room and i can’t use the ac at night so i dont even sleep in my room sometimes
but i’m looking for any advice i could get on how to keep the crab warm in my room but maybe turn the ac on for me

Do you have an under tank heater (UTH) on your crabitat?

The uth should be located on the rear glass above the substrate.

Here is our care sheet about having a proper tank set up. There is a paragraph that mentions the uth.

Here is a guide Fleabag made for setting up an uth on the tank. Based on your location and conditions you may not need to cover the entire back.

i do but i’m worried because if i put the air conditioner on that it wouldn’t work or it would get way too cold

So your tank is at 75 with the uth on and no AC in the room? What brand of uth do you have? Many say Zoo Med doesn't work well. Ultratherm or Fluker's tends to be more efficient, and may heat your crabitat better so you can keep the AC on.

I use ac in the room with our crabs with no issues. We use insulated ultratherms with glass lids and have never had an issue with the tanks dropping below 77.

Most UTH's are made to warm a tank up to 10 degrees above room temperature. That is is you have the correct size heater and proper lid to hold in the heat.

In the winter I will add a towel to the top of the tank. That will usually bring the temperature up a degree or two. That is one possible option. You can also make sure your tank is not in direct line with the AC too.

thank you for the help!!
i have a mesh lid top and am looking into another one for my 55 gal (it came with the mesh lid so that what i was using)

In the mean time you can seal the mesh lid with plastic wrap. It will help out some.

Don't worry the crabs won't suffocate. The air will circulate when you do your daily maintenance!

I have the mesh lids (made for reptiles) I had a piece of glass cut to fit the mesh part and duct taped it down. Works great.
