Hi everyone, I just picked up one of these from B&Q over here for the cost ofâ‚¬8.80, in the UK these are only Â£6. Basically a heavy duty water syphon. Total length of the hose is 12ft or 365cm, comes with a hose connector to add extra length of hose if needed. The only drawback I can see is the hose length from the syphon (bit that will go in the tank) is a bit short at 50cm but you could easily add some extra hose here, even comes with a sucker to attach the hose inside the tank wall, way better made than one I had purchased from a well known online vendor some time back. It won't suit evenyones uses for water changes but perfect for me, anyway handy piece of kit for only Â£6.
