I added mesh as well. But the bottom line for me was how the hell did he manipulate his body to fit. He could potentially just perch/mount/set foot on it and ruin the return/drain ratio and potentially overflow it. He doesn't necessarily have to enter it to mess things up. Right now I have both mesh and Eggcrate creating an unsightly "barrier" .. Still not fail proof.
I know they sell mini float switch that could be mounted by drilling a hole or mounting to acrylc. That's my plan.
This morning it was sitting on the drain.... Think i am going to take it out. The rbta is the only one moving in the tank. My green one is sitting at the very top and hasnt moved since i got it.
Nice setups you have their.. lovee it
Thanks!
