I've been using the gravel vac I got for my 10g to vac my 20g and 10g but I was wondering if it would work in my 55g since the 55g is taller than other 2 tanks?
Well I knew that in my 20g and 10g the water only went up to about half my arm but when I stick my arm in my 55g when I was putting the plants it went about my elbow.
