what is it you want geoff.. is it to attach the hose to the side of the tank so that you can walk away and leave it?
would you want one that has suction cups on or one that hangs onto the glass its self... this is dependant on hood style
the reason i ask is that i have one if you want it.. im just googling to see if i can find a pic cos i cant be bothered uploading a pic at ths time of night
7th item down.. u can only just see the clip, but the hose feeds thru it and it then hangs over the side of the tank, clip can also be squeezed to stop water flow
