As a fish keeper I have had to deal with all the waste fish put out. To maintain a healthy environment for these animals you have to change the water frequently, which results in quite a lot of water being wasted. You may have heard of hydroponics, which is using water and some sort of medium to grow your plants. There is also something called aquaponics. This is using fish waste as a fertilizer and nutrient source for your home grow vegetables. Fish waste is very high in nitrogen and nutrients which is perfect for plant food, and the continuous cycle of fish waste being produced means an ever lasting source of food for your plants. It is very easy to set up a system like this too. All you need is a small tank (10 gallons), some sort of hydroponics media, a water pump, and a small clamp lamp to provide the plants with light. The waste filled water is pumped up from the tank and through the media, feeding the plants, and then the now clean water is returned to the tank. Its killing two birds with one stone, keeping the fish water clean with out wasting water, and also gro wing your own organic food for you to eat. I have used this on one of my goldfish tanks and it works amazingly. What do you think??

I think this is a great idea, I have always wondered where the tank water goes, I knew there was filters, but I never knew it could be used in so many different ways. I believe it is very important to conserve all of our resources, and especially in California where I live right now, we are experiencing a bad drought and conserving water is very important. I also did not know that fish product was useful in growing plants, I had never heard that before and I think it is a great idea to harvest as much as possible to help the environment in any way possible. I also like that you know so much about how to be sustainable when it comes to something as simple as fish. If everyone figured out ways to use their pets an things around their house to be sustainable the world would be much more clean, and the environment would be safer and healthier.

My uncle does this and he saves lots of water. He filters out the waster water and tries to use it again

That is a great scheme Mr. Burger. I never thought of using fish waste to reduce CO2 emissions and keep a clean environment. Despite not having a PHD in Fish Keeping, I do know that a filter for the water could make some difference. Whether or not it does as good a job as your idea, I have no clue. Although, maybe someone educated in this field of study could add to your idea and take use of it. So as I said, that is a great scheme.

Wow Alex! Great Point! For the past two years my dad and I have fished a lot and have never thought about aquaponics. That sounds like a great water saver for fishing especially fishing lovers. Next time I go fishing with my dad I will talk to him about it!
