Safe Alternative media's ?

I don't know if someone used to absorb oil is a good idea to use in a fish tank. wouldn't it just soak up the water. Why not just stick w/ traditional media it's not like it's that expensive.

Hi. I haven't found a thread listing the diffrent filter media alternatives that are safe for use.

Some of you guys ever tried those crushed walnut shell socks? or the oil spill media the ones you can buy that you can dump your car oil in?

What are the media's that everyone else is using?

There is a list of media in the stickies. Just about everything has been tried and unless you can get it free, scrubbies win out on cost vs surface area/lifespan/clogging/cleaning etc.

Absorbant materials are designed for skimming not to filter and have a very poor thru flow if any at all.

Also some automotive oil absorbents are just dry clay like cat litter and dissolve in water.

Are you looking for a specific function of filtration (sump/canister/HOB)?
