You know what's just as good as compost tea for your plants? Need a hint? Well there's a big hint in the title of this post. Give up? Yes, it's fish tank water.
Fish tank water is a great natural fertilizer. It's loaded with fish poop and it's a scientific fact that plants love poop. Well that's what I heard anyway.
Once every month or so our aquarium needs a water change. About 40 percent of the water is removed along with a lot of the sediment thats sitting there in the gravel. This is done with a tool called a gravel siphon which is just a big plastic tube that you jab in and out of the gravel. This jabbing stirs up the muck that's in the gravel while it siphons out the water. A typical water change for our tank will fill a 5 gallon bucket. I used to pour this water down the drain but now I know better.
In the summertime, this water will go directly into my garden beds or the compost bin. Winter water goes right into the house plants.
Since I started using my fish tank water as a fertilizer, my plant look shiny, healthy and I'm no longer wasting this perfectly good water.
