Bio in tank filter

#1
I wanted to make a bio filter using a soda bottle, air, and some sort of media. I used suction cups attached to the bottle to hold it in place. Rubber bands were used to hold the airline in place. ( the rubber bands seem to rot very easily) Looking around I found at "The Dollar Tree" store small hair rollers that had a plastic covering with what looks like round tipped fingers. I pulled the cover off the roller and cut them into small sections.

The fingers stuck to each other not allowing for circulation of the sections. I turned all the sections inside out. This worked and I had a working bio filter.

I wanted more surface for filtration so I again pulled all the media out, cut many more up turning them inside out. Some of these I put inside one another sometimes putting three together. They look like little bio spears. The picture does not show the finished media very well.

The advantage would be not needing to clean the media as it cleans itself from the movement and interaction with each other. I was trying to come up with a cheap replacement for K1 bio-media.

I have made my own sponge filters since I built my hatchery several years ago. They work very well as we know.

Hay who doesn't like seeing a pink flowing mass of cut up hair curlers! :P

God listens. He may not always give you everything you want, when you want it; but he always gives you what you really need, when you need it most!
