Hi,
I have just got my fish in my new tank and am thinking about when i come to cleaning it for the first time? I have gravel at the bottom, and have found on amazon a gravel cleaner? just wondering how it works and if anyone has any other ideas?
here is the link for the item i found:

Aquarium fish tank BATTERY powered vacuum syphon cleaner: Amazon.co.uk: Garden & Outdoors

Thanks guys xxx
