The trick would be designing it to where the plants could have a good grow medium/substrate and still achieve good water flow. This would definitely be more effective for aquaria where you couldn't have plants. I have considered using 'old' water from my non planted aquariums for water changes on my planted aquariums and dosing less nitrate and phosphate. I think for good sump growth you may need to toss in some micros and potassium from time to time.
Lol. I will be the first to start that journal. I wonder if I could do it not.....?
Anyway. My biggest point behind this was to point out how it would benefit fish only tanks, where you cant have plants. I am thinking baffles in the sump, and a high turnover rate. Also you would probably benefit from using faster growing plants as they will suck up nutrients faster. This also could help the fight against algae. And I think, emersed growth would be key. You wouldn't want to inject a sump with CO2 just for the plants in it. I think they would take enough from the atmosphere, like you said, but they would also get plenty from fish. And sunlight would be a plus. If not that, maybe high light. And you are probably right on the micros. That would be easy though.
I wonder if anyone will put this to use and start a fuge on their tanks? Lol.
