some help needed

[islandvivs]

hi guys, my first post here. So iam building this vivarium with rock wall and fake egg crate flooring. Anyways after all the construction part was done and i realised that although i tried to fully seperate the water area from the land area over time there might be some water seepage under the fake egg crate flooring....so my question is can i put some kind of substrate(other the LECA) to absorb the moisture seeping in eventually.
thanx

That is the whole purpose of a false bottom. Eventually the water from misting will make its way under the egg crate and once the water level is high enough you can siphon some of it out. As long as it does not raise high enough to come in contact with the bottom of the substrate it is fine.
