Review on Aqueon QuietFlow E Internal Power Filter Large - Efficient Filtration for 40 Gallon Tanks by Michelle Frey

Well, the name speaks for itself. The filter measures about 10.5 inches top to bottom and the only way to make it really quiet is to mount it with the 4 suction cup option (rather than hanging from 2 clips - another option. This means, that every 10 inches is visible in your I like to over filter a bit so it's actually in a 30 gallon tank but rectangular so not really that much smaller than a size 40. Water splashes like a waterfall and I am used to an internal filter with a very low noise, when installing inside with suction cups I have to be very careful about the water level, otherwise the filter is completely submerged and as if the incoming unfiltered water is going through the back of the filter sump, through the foam - and carbon filter can overflow Very bad, since now my aquarium does not fill to the brim - there is a 2.5 cm open glass over the top frame Still quiet and the filtration looks good a us for the first two weeks Note: >>>> pa Measurements are very close to: 10.5 top-bottom. 4.0 front-rear. 6.0 side by side which would be about right for a mounted filter but big big for an internal tank. PS: Comes with some $2 coupons for Aqeon fish feed and supplies. Didn't really look at her.
