Cascading and drilling 20 long tanks - reality check/help needed
I'll preface this by saying I should really avoid browsing sale ads, because they result in finding things like this:
That'd be a tricky tank to run heavily planted, but it did get me intrigued by the concept.
Rather than stacking tanks vertically, however, I'd like to try aligning a trio of Marineland 20l tanks like stair steps, cascading into one another along a section of the the long edges. It would provide a lot of oxygenation, and the fish I keep really like this sort of thing.
I'd ideally have an overflow (mini beananimal?) on the lower tank draining into a sump, then a return pump to go up to the top tank again.
1) can the ends of Marineland tanks be drilled near the top edge for overflow pipes?
2) can anyone think of a way to arrange for a controlled overflow on the top two tanks? I'd love to grind a notch in the edge of a derimmed tank, but that seems unsafe lol (not even sure if it's possible). I'd like to keep the overflow contained to a few inches at most, since we generally view the tanks along the long edge.
3) could the tanks be safely drilled near the bottom for another application? They're not deep tanks, but I'm not sure how structurally redundant the design is.
Thanks! Might be just a pipe dream, but it would be a way of getting more enjoyment out of the tanks I have instead of buying bigger ones.
