I don't see there being any component of a low fish high plant system that would require more work than a plenum (nitrate reactor) I built one of those when I was breeding corals, and it was a lot of work to get it running, and I did a lot more testing after that.
nitrite build-up usually occurs during the winter or cloudy weather, the greens take up the nitrogen faster than the plant can process it. the system of light/heat is unbalanced - it is warm (summer) but the light level is low (winter)
this occurs also in soil based green house systems. one solution is to remove the plant with roots from the aquaculture system and put it in clean water for a few days with sunshine or lights. this will allow the plant to utilize the excess nitrogen

I think what interests me the most is the prospect of cultivating a mineral dense freshwater weed so I don't have to buy in kelp for the garden or the animals.
as for water based plants i remember reading about water cress. i know cattails are more of a permie/forager thing than market thing, but how would they do in such a system? are they a 'water' or a 'land' plant?
certainly, but in the case of nitrates in greens, how would a backyarder know it was reaching poor levels?
i'm with you silverseeds all my research over the past 5 or 6 months agrees with you. i never really pieced together in my head that the major difference between the potential that i first considered and the negativity i was reading is that the problem is land based plants.

thanks for the info, i have a reemerging interest in this. we are looking to start with 1 tank of fish and 1 tank of clams.
i was actually pretty high on my results with my snail tank, but while i would consider eating snails, (not these these are more like my pets now) i would not cook them before eating them. and i have trouble cooking things alive also. (part veg, fish no meat for me)
