Aquarium Water as Houseplant Fertilizer: Always

» biogardener - Always

If your fish water stinks, you are waiting too long to change it. That is not healthy for the fish. I have used syphoned fish water for houseplants for as long as I remember. No one told me to do it. It just seemed the natural thing to do. It has never been smelly. I change the water about once a week, removing 25% of it. In the winter, I replace it with water which has been standing in gallon bottles for at least three days. In the summer, I use rain water, in fact, I save rain water in gallon bottles for the winter.

I syphon the water directly into two litre pop bottles which I place in a pail just in case I overfill one. Then I close the pop bottles and keep them close to the plants. I make sure that I do not use the same size of bottle for the fish water as for the replacement water.

I have the healthiest house plants you have ever seen.
