Also, instead of filter. I can just use 3 pumps. And under the rack I can put a sheet of small mesh. Because the poop will fall into the mesh which would be clipped on to the tray. Which upon removal I can clean the mesh or use new mesh. I can use double mesh to make sure that poop stays in but water goes through in form of droplets. I can add drift wood to make it look natural too. Idk if this would be similar to a rainchamber but it would be nice. Especially for arboreal frogs because then you can have a tank that is say 2-4feet tall. OR you can get like a 20g turn it on its side! Or a 30 normal g. Then you get like 2feet of tallness. Itd be nicer if there was a 4foot tall tank. Like something similar to exo terra. But like the tank would be 3-4ft tall, 1ft wide, 1-2ft long. :P With that thing the exos have that lets you open it. SO the bottom would be plain water, and the sides would have plants instead of how I mentioned it. But still with the racks. To prevent anything to go bad. :P

COuld anyone please give suggestions or anything?

Also I was thinking id time the rain to 3-5hours a day. During night time or day time. Scattered rains.
