i disagree on removing the fish aspect of it. the fish will be fine, they will simply avoid the gravel vac. removing fish can be even more stressful you know. when i had my bigger tank, it took me at least half an hour to net 1 ram, he Really didn't wanna leave the area he was used to - decorations or not. and can you imagine removing delicate fish like discus every time u need to vac? that would be a disaster :/
also, on the package it says to jam it up and down to get the water going, but i find it easier to just suck the other end of the tube one time. you can youtube it, a lot of ppl use different methods, but i think the directions use the hardest one lol
if you have a lot of decorations i would suggest removing one week a few, removing another week another few and etc. basically rotate removing decs. debris gets under and in them
