The pump was easy to install, it works just like it should, and it was delivered rapidly. The price was not out of line compared to other options, but everything is overpriced these days.
Verified Purchase
This fabulous filter, comes with one filter cartridge. Water flows beautifully in a small tank, mine was a three gallon. keeps water clear. Very nice ,not bulky, thin ,fits nicely over the back of aquarium with the main filter internal.plug in cord is a nice length . Great for a fish tank. i have guppies , a catfish and a large snail.ThanksTetra Wisper, price was very good as well.
Verified Purchase
it's just perfect for a small little tank. read some stories about pumps killing fish that get trapped on intake holes but my fish has been just fine for about a month now. the intake suction is small and on bottom as well.
