I am wanting to get rid of the filter on my tank and was thinking about something. If I take the sponge out of my filter and wrap it around my airstone will it work as a sponge filter? Also I want shrimp but my water does not have enough calcium. I have been using an unknown gravelly substance my LFS gave me in the filter but I want something easier to use with a low flow setup like just described.
Any help appreciated! God bless!
