I need ideas for rain chambers

[Kurt]

I would show you my diagram, but I can't find the disk that it is on at the moment.

Here are some pics of my system so you can visualize it. In the view under the stand, the blue pump on the left of the big filter is the rain pump. The other photos are of the system running. After the eggs hatch and the tads fall into the pond below, I remove them and place them in the tadpole rearing tank....the last photo. Hope this helps.
