We have been frustrated for sometime with not being able to keep the water clean in our fish pond. No doubt the pump size is inadequate for the area.
So after much pondering, my husband Michael came up with this idea. It works a treat and is basically a plastic crate that has 3 layers of foam inside, and an extra hose, which feeds from the pump- through the foam, and then comes out clear water.
Each week, all that is necessary is for the foam pieces to be removed, hosed clean and put back in the crate.
The fish are happy and so are we.
