well i personally dont like there "water out" system because it could get clogged i do like having a drainage spout on it, and i have a pretty good idea of how i am going to do it. And i will be using beanie baby containers, it it can be easily removed it i need to transport the fish. As for the PVC and the beanie containers i will make cuts as needed. There are 2 ways i would like to use the beanie containers and the drainage spouts. I can either have the beanie container sit beside the drainage spout and have an 90 degree elbow coming out of the beanie container and then the water flows through the elbow and into the drain which is slightly raised on one side so it will drain properly or i can have the beanies sit on top of the drainage spout and just cut s slit into the back of each beanie and the water will over flow out of that slit however i dont know how to do this without have the beanies on one side slightly raise higher than the other side so it will drain properly. I dont know if this is understandable or not but i will take pictures of it as it comes along, but right now i am still in the planning stages
