How can I lower the humidity in my tank?29 gal with 8 inches sand/eco earth substrate

You can open the lid a little to vent some of the humidity just make sure that none of your crabs can reach the top and push their way out otherwise you may have an escape issue on your hands.

Thanks Crabber85. I always feel better when following your advise.My humidity is setting at 75 & temp is 75-76. When I was planning things out I wasn't planning on this big of tank. I'm going to have to find a bulb to provide more heat for my 29gal tank.

@jasonmom, I appreciate the vote of confidence it means a lot that users here trust me.

I do that to let out humidity but with in 20 mins it just goes up I'm thinking of mixing in dry sand to bring it down a bit in at 88 most of the time sometimes 90.
