Recycling aquarium water

Well heres my plan. In spring time im going to have a lot of plants outside my room on the balcony. I would like to grow vegetables etc. I plan on using aquarium water to use on the plants. I thought this would be a good idea since aquarium plants use nitrates in the water, why wont gardening plants use nitrates? Would this work as a fertelizer/water or just water.

I was reading on another forum some time ago (the krib, I think) about how water from water changes makes the best possible watering water for orchids. If Orchids like it, it should be fine with vegetables.

Logic is only the beginning of wisdom

By the time the plant uses the nitrates for food, the biproduct would be non toxic for humans in the situation you are describing. I use aquarium water to grow awesome tomatoes, spices, lettuce, and other veggies. I also use my pond water for watering my veggie garden a few times/month. It's the best fertilizer you could ask for, and its free!
Happy Gardening!

I grew roses, crysanthemums, cabbage, romaine lettuce, green beans, lavander, and pretty much anything else IO wanted using tank water from water changes. The plants absolutely loved it and I never had a problem. The slugs didn't like it though.
