I am going to get her another wheel anyway as it sounds like she might have some how worn this one out. every so often I can hear a grinding noise then it will stop when I check it out. it's been driving me crazy! it might be because it is not sitting flat on the tank Base and is sitting on the substrate so the spindle is at an angle so I may have to find a bit of think wood for it to sit on.
