hey new to the site, new to vivs/darts..my question is i have set up my false bottom egg crate i will be having a water fall. my thing is considering the water needs to be at least 1 inch in the bottom of tank for my pump to run do i just let the leca sit in the water or above the water? if above the water line do i just leave the false bottom empty minus the water so my pump can pull the water for the falls?? thanks sorry for the newb question

Here's a handy image of how the substrate layers in a basic vivarium should look. Since there will be standing water at the bottom, you may want to go with 3'' of hydroton (aka leca). The bottom 1" of hydroballs/hydroton/leca will be submerged in water.



There will be a new blog posting tomorrow discussing the different layers of a vivarium posted here:

crap. actually i have a false bottom thou..so it would be best to just put leca on top of eggcrate than do my layers of soil etc..so underneath the false bottom will just be water for my waterfalls? would that be better?? so i would go..

Eggcrate method replaces the leca method. They both do the same job as far as uplifting the soil above the water table so your soil wont get water bogged. Using the eggcrate method makes the vivarium lighter. Make sure you put support in the middle or any where else you think it will fail if you put lots of weight.

3-4 inches of eggcrate
mesh
abg mix
sphagnum moss
leaf litter

Hydroton provides a lot of surface area - similar to bio balls. I also prefer hydroton because it wicks a bit of water back up into the substrate, helping to maintain humidity.
