I have used the water change and filter debris from my tropical fishtanks to water my houseplants for many years and wonder if there is an excess of one or more possible plant nutrients contained in the water. Nitrates feature large in written material about the waste products that build up in a fish tank. and in other literature concerning plants nitrates are considered beneficial. Any ideas about the advantages or otherwise of this practice would be appreciated.

I've asked the same question and people are torn. Some will say no because of the salt in the water and others will that they've been using aquarium water for years without problem. I would really like to know because I have to fresh water aquariums and will be getting a 55 gallon soon and I just hate to dump the water where it won't get used on something useful. I would think that as long as your tank is cycled the water should be just fine to water plants with. After all, I have live plants growing in my tanks.
Here are some quotes from sites that say it is okay:
"#26. When you clean your fish tank, use the water you've drained on your plants. The water is rich in nitrogen and phosphorus, providing you with a free and effective fertilizer."

"House Plants & Fish Tanks: If you have a fish tank, you probably clean it regularly. Use the dirty water to water your house plants. It saves using the same water twice, and the plants love the water, which is rich in nitrogen and phosphorous!"

Correct. Plants actually drain the soil. Ever notice you have to add dirt to a plant after an extended period of time? You are just partially replacing what they use.

No you are doing the correct thing.I had a 2 ton tank and used a big pump to do a water change,i pumped it out over my flower beds in the front garden,and they did very well on it .my smaller tanks were pumped into the rear garden.

It seems to be "all good", I never seen anything to the contrary. I too have used it for years and have never heard one of my plants say it didn't like it. RScott
