Which pump is suitable for the sera gravel cleaner?
Which requirements must an air pump meet so I can remove sludge from my aquarium with the sera gravel cleaner?
it must push the air up to the bottom end of the sera gravel cleaner (where the air passes into the main tube), that's all. Our sera air 110 plus is usually sufficient for this purpose. More powerful types (e.g. sera air 275 R plus) are recommended in case of deeper water.
Do I require a separate air hose?
No, you don't - the air hose is included with the sera gravel cleaner.
