Hello, I have a bottom drain that sucks in water to the pump to feed the waterfall. Attached is a picture of what is connected to the drain and I have a larger cover over it, which looks like a big strawberry basket. The bottom of the pond has gravel and is uneven, so the larger cover doesn't sit flush to the floor and some fish were able swim up under the basket and they got stuck to the drain cover. I put some rocks there, to cover the gaps and I hope this works and they can't get close to the actual drain, to get stuck to it. Does anyone have any other ideas? Thanks
