Interesting concept. What I dont like about it is that the amount of fertilizer you are getting is dependent on those membrane "stickers". You have to pick which one you want to determine the flow of water between the membranes. The amount of ferts you need is dependent on quite a few other variables other than size of the tank. Though I suppose if you need more perhaps the fertilizer would run out quicker. I wonder how well that would work for a bigger tank. My only question is what happens when other matter gets dissolved into the water column...say fish food or waste, or decaying plant matter. Will that mess up the dosing...or will it in fact help because the dosator wont be pushing as much ferts into the water? Hmmm...very interesting.
