Hydroponic aquarium (with live fish) garden?
First time poster, here, and I have what I think is a pretty different experiment I'd like to try. I haven't seen much about other people doing this, so I'm wondering what some Garden People think of this.
I have a 75 gallon fish tank that I can't put plants in (African Cichlids pretty much destroy any plant I put in the tank). Plants have the obvious effect of removing nitrates from the water which improves their water quality. I'd like to do a little "refugium" on the back of the tank where maybe I could grow some very basic veggies using a hydroponic setup. Basically, I would use a filter (it's a little different than a filter, but itÃ¯Â¿Â½s a good way to imagine what I'm talking about) on the back of the tank, and plant some stuff in it. I could have new water come in as fast as needed. Anywhere from like 200 GPH down to 1 GPH every 24 hours or something, if needed. The water PH with these fish is high, about 8.2. I was thinking I could plant stuff in gravel maybe? I can't really add much to the water as far as plant nutrients go, as this water will be 100% shared with the fish.
Does anyone think I could make this work? Would certain veggies work better than others? The tank gets light, but no direct sunlight. I could add a little bit of lightÃ¯Â¿Â½ but not much.
