Hello people. Just joined this site. I have a small 60 litre goldfish aquarium and also have just had delivered a 100litre aquarium as am going to set it up for tropical fish. I am a complete beginner when it comes to tropical and am so excited to do it as I think it would look beautiful. I have bought some ornaments and have all the bits that go with tank, heater, pump, thermometer etc. I have come across a small problem though before i start setup today. When I bought the accessories at the fish shop I bought a hoover that sucks all the waste and food up off the gravel. Thing is because my tank is more in depth than width, the hoover can't reach in long enough without getting the mechanical parts wet. (It's battery operated) is there anything I can do to it or buy for it to extend it so it reaches down? Thanks for all your replies in advance.
