Waterfall issue-help!

[jakeyost89]

Hey guys, i currently have a 29gallon tank with a false bottom and a water fall on the left of the tank. Currently my waterfall is set up with a small pump that feeds water through a small filter and runs the water done what's supposed to be used as a cave, but works quite well as a feature for water to run down. The water runs off of this into a water dish which i have surrounded by gravel, which the water overflows this dish, runs into the gravel and then drains into the false bottom. A little less than half of my tank is covered in gravel around this dish and the rest is covered with ZooMed's Eco Earth. I'm having problems with the substrate sticking to my animals and then it being carried over to the water. It then drains out over the dish into the gravel and starts filling in all the cracks. This causes my water to have a yellowish brown tinge to it as well as makes the draining an issue, where it will drain closer and closer to the substrate until the water is overflowing from the dish, flowing to my substrate which then causes it to be soaked. Am I doing something wrong or is there something I can do to prevent this. Im having to dig out and clean my gravel about every 3wks, and I hate disrupting my animals. Any ideas??? Thanks!

leaf litter might help to keep it off the frogs so the frogs can't bring it into the waterfall.
