My experience with this product is that they clog quickly and become useless in just a few months. I think the basic idea is sound, but I don't think this is the right product. Large & long airstones are probably a better choice. I've used them in my aquacube for 2 years+ with no issues.

I don't think many plants will like this arrangement though, but you'll need to try and see. It does seem energy intensive.
