Hi All,

Does anyone know where i can purchase some large black filter mat? I know there's 25 and 40ppi. Any other recommendations?

Here's the tank. It's an old pic. There's plenty of plants now :)

Provided you've got good water flow the recommendation is generally 40ppi, you just need to ensure you have a good return/outlet for the water so that you

get a good current going through from one side to the other. As to where there used to be somebody in Melbourne that sold it but no idea on sizes etc.
