I change the water in my large goldfish tanks every week and I use the "dirty" water on the plants in my garden.
If it's not to daft a question, can anyone tell me what will be in the old water such as fish poo, dying plant matter etc. I'm asking because my plants do really well and a fellow gardener has asked if he could buy a fertiliser for his garden that had the same or similar ingredients as the old tank water.
