Blutails Aquarium Internal Filter | SOBO WP-1000F 4 in 1 High Power Biological, Mechanical, & Chemical Filteration System |, 15W AC 220-240V MAX Output 650L/H.

This filter is compact, easy to clean, and quiet if set up right. It's unfortunate, however, that it's so fussy to set up properly the outflow bar is nice. You can set it underwater to push straight up or against the glass for no sound. Or you can set it above the water line for some nice fountain or running water sounds. I love that you can use your own durable filter media. You can throw in whatever you want or buy pre-cut foam. It's easy to access and replace.Everything here is hard plastic press fit. You need to be gentle and get some water on the fittings for it not to crack or break while twisting around.

Quality is medium

Very large for my tank. My tank is 1ft x 2ft x 2.5ft. (w*l*h).Have to control flow otherwise my fish cannot swim and gets stressed.Also after two months it keeps stopping. Have to clean it again and again and keep watch.But then I couldn't find any better options than this one. This is submersible, takes less space. Helps fish hiding, doesn't suck up fishes.

Works as intended. Leaves the aquarium clean.

Quality and performance as expected. Suitable for larger tanks. For small tank, turbulence is more due to more water flow.

I like it.

The media could not be loaded. Received good condition...Wonderful working
