ok i thought of this earlier, i use the false bottom thing but with a plastic sheet as the bottom ( holes drilled in it) with one of those substrate-proof screens. After you have the false bottom, make a hole in the plastic on the end just big enough for the pvc to fit through, connect a tube to the pvc and run it out of the cage and to a filter (i was thinking a small bin with sponges in it and maybe even a charcoal filter inside) instead of running it over the top, have a hole with a barb coming out of each side (the thing tubing connects to) one side being intake one side being output and on the output side run a tube to a small pond pump. after all that is done run a tube from the output of the pump up the side of the tank connected to a garden hose sprayer (with a barb) all running on a timer
anyone think this will work?
