Guest bikeboy19 Posted January 8, 2008 Share Posted January 8, 2008 Hey I have a bio-wheel 350 with the extra slots and I was wondering what others put into their hang on power filters. I curently have the marineland filters and filter bags full of Seachem? Matrix? Biofilter Media in the extra slots. Link to comment Share on other sites More sharing options...
Regular Member Earth!Mother Posted January 8, 2008 Regular Member Share Posted January 8, 2008 If you have the extra compartments. I keep crushed oyster shells in one, to up my KH, I'm hoping this will help. I also have snails, and I heard that they can help with their shells.

Guest bikeboy19 Posted January 9, 2008 Share Posted January 9, 2008 I was reading more on this and should I be cutting out the carbon in the marineland filters, and i was wondering if the seachem stuff in the filter is a good idea? Link to comment Share on other sites More sharing options...
