Vacuum Cleaner For A Tropical Fish Tank

Hi All what is the best Vacuum Cleaner for Gravel Bed for my fish tank one will take all the crap from underneath gravel some you get leaves the water in tank I have seen and read on facebook don't know what to do and buy

I have had about 16 gravel cleaners over my 16 years' fishkeeping, probably because I've never quite been happy with any of them. However, the one I've stuck with the longest has been this https://www.jbl.de/en/products/group/4035/gravel-cleaning - I use the smallest one - as I find, with the optional black 'grid' removed from the wide end, it gives exactly the right amount of sturdiness and suction strength that I like. I've found that other brands' tubes are either too flexible (and kink/block easily) or too inflexible (difficult to navigate round the tank), the portion attached to the tube either too short or too long (and makes for clumsy use), and suction too weak or too strong. This is entirely personal choice, of course, but is definitely the one I've got on with the best.
