Fish Fanatic
I always use one of the Algarde gravel cleaners, you push end into gravel and it agitates up the tube to clean - always found them very good - however fish are getting a bit bigger now plus I have a plec in there and I am getting lots of long strings of poo ! - oh joy !, find these tend to just float around in tube and dont' really get sucked out. Do I need a vacuum - not sure how these work, or exactly what they are best for. Any advice and/or recommendations of brand would be great
