I have a Marineland HOT pro (biowheel) with the huge carbon container. I would like to stop using carbon. What would you all suggest I put in the container? Filter floss?

I'm not personally familiar with that particular filter, but they probably make an alternative insert for it that is just some type of filtering medium. Otherwise the filter floss should work.

Hi,
I hate filter floss. It brings back memories that are
30 years old. I would use a piece of sponge cut to fit
in the enclosure. You simply drain the tank into a bucket
while doing a water change, and squeeze the sponge out in
the old tank water, and replace the sponge back into the
filter. Nothing could be easier and the sponge will last
years before many fall apart. Why mess with that stuff
and throw it away after a week or two?

I also hate filter floss. Are you looking for more mechanical filtration or chemical? Since you mentioned filter floss I would guess mechanical but there are other chemical medias. The problem with fitting something in the cannister section of the magnum is the shape and water flow. If yours is the same as the one I used to have(and cursed for months before throwing it in the trash) it's just a big empty cylinder in the middle that the water is suppose to flow through. Coarse filtering ceramic noodles would be easy to use, reuseable, and wouldn't cause water flow problems but your already filtering through a medium filtering material before it gets to that point so it wouldn't add much mechanical filtration and you have biowheels so it wouldn't be useful biomedia either. You could buy strips of filter material and cut it to size and either try to wrap it around the inside of the cylinder or lay down layers in it. That might be effective. Cutting down a big sponge or several litte sponges and jamming them in there might work too. Otherwise you can just try stuffing a bunch of filter floss in it and see how much of a pain you think it is. This one might take a bit of experimenting to see what actually collects debris, doesn't mess up water flow through the filter, and isn't too much work. I'd probably try getting a long roll of filter material like this [link=http://www.drsfostersmith.com/Product/Prod_Display.cfm?pcatid=4318&amp;N=2004+113808]http://www.drsfostersmith.com/Product/Prod_Display.cfm?pcatid=4318&amp;N=2004+113808" style="COLOR: #C000C0[/link] and wrapping it in a circle around the inside of the cylinder.

Thanks for the info.

I think I may go with Purigen.
