Quilt Batting as filter material

7 May

If you use LOT of filter wool, either in indoor tanks or a pond, consider buying Quilt Batting. The regular batting is denser than Aquarium filter wool. The batting does not remove the finest algae particles but it collects more than the Aquarium wool.

I cleaned the pond filter a few days ago. Here is that process. It’s a cheap filter, supposed to work mechanically¬† (with filter wool ) but also biologically, with plants growing in the filter itself. Unfortunately, it is so brutally hot on the South side of my house that no plants have survived in to the Summer months. Plus, the turtles eat any aquatic vegetation in the pond, so this filter cannot keep up. Still, I would recommend something similar for a goldfish pond. (NOT a Koi pond, same problems as the turtles)

The empty filter. By the way, this is just the “filter box”. The pump is underwater in the pond and tubing runs into this box then overflows into a small stream.

2 bricks on the bottom. The water comes in through the white PVC tube at the back left. The bricks will support the rest of the filter material so the water can flow around underneath and percolate upwards.

The white grid is some of that “light diffuser”, plastic stuff that I use to breed egg-scattering fish.

Plus some Lava Rock.

Quilt Batting.

Another grid on top.

A strainer around the outflow.

Rocks to hold down the grid and the strainer.

And I still have green water.

It’s green, it’s clean, but the fish cannot be seen.

I realize that I failed to show you the real fun part, which is crawling and crouching while removing heavy, nasty, disgusting old filter material. Since I forgot to take photos of that please use your imagination.
