Review on DaToo Aquarium Hanging Waterfall Filtration by Dandy Sulley

I'd read reviews about it being small, but I still wasn't prepared for how tiny this filter really is. I matched it to my 10 liter tank. It didn't fit around the black plastic flange on the inside rim of my tank until I lightly shaved the flange off with a precision knife. The flow seems normal for the size of the unit, although I added an air stone to my tank just in case. The cartridges supplied are of poor quality. All they have is a very thin transparent membrane on the outside and you can see there are about 30 grains of carbon inside. I plan to try remaking the cartridge to make it work a little better. Overall, this unit is clearly intended for a nano aquarium, but with care it can do for 10 gallons as well. The reason I chose this one is because I read several reviews of other devices that seem to suck fish in their fins and this one doesn't seem to have this problem.
