Strong enough to clean a 100 Gallon tank
I havea100 gallon tank and my large auger that l hook up to my sink would not suction properly so l had bought this one for my smaller tank and really just got tired of trouble shooting the larger one for now and needed to do a quick water change so l used this. Wow! It cleaned the heck out of my substrate. I use a large clean trash can to empty the water and  yes with a tank this size l had to empty about 5-6 times but if you have wooden floors like l do it wasn't such a pain. I was even surprised at the amount of power it had in that much water. Nice backup
