It's just going to be a case of trial and improvement with the waterfall/ rain fall system.


My plans for setting it up were a pair of meshes. A load bearing heavy mesh on a stand system. With a fine substrate gauze on top.

With that in place i was probably going to use a cat litter tray or something similar to line the bottom of the tank. Provided the fine mesh is cut over size so it not only meets the edges of the tank but gets forced up by them it should keep the resovoir clean. It should also stop the frogs been able to get into the resovoir.

Water should freely flow back into the reservoir. but you may need to remove the filter to get the pump to fit, the substrate will do a lot of the filtering with this setup anyway.
