NICREW Aquarium Internal Filter, Submersible Power Filter with Multiple Function for Fish Tanks 5-10 Gallon, 53 GPH, 5W

El artículo es muy chico, se tapa constantemente el servicio que da no ca de acuerdo a su costo.

I bought every adaptor I could find and still cannot plug it in properly. Very annoyed that it even needs an adapter in the first place. Basically unusable.

Works great for my 5.5 Gallon tank, I actually modified it some in which then it works even better, inside the filter is a plastic basket that holds a small pouch of carbon, the basket has small holes, so I actually used the Fluval Zeo-Carb loose in there, it is big enough that nothing escapes! Works great! Then I trashed the little pre filter that comes with this, I felt it had large pores which let a lot through, and I got the Fluval Phosphate filters, and I cut them to size and put them as the pre filter, I think it makes it one of the most efficient filters I've ever had, and it SUPER QUITE I love that if I keep it just slightly above the water as it sprays from the long attachment it creates some bubbles, enough that my guppies are super happy, which is good because typically bubblers are very loud.

Super fast delivery. Awesome price. Almost want to get another one, just as a back-up. Only complaint, as silly as it sounds; It's almost a little too powerful. Didn't see a dial or adjustment knob. Thing is rad.

It works as filter should. But it would have been even better if it had flow control. I planned on using 2 of the 5-10 gallon size for my 20 Gallon Long tank. Bought 1 to try it and one unit was already too strong for my tank, I had to wrap the spray bar with some filter foam so as not to create too much movement in the water. I wish Nicrew would put a flow control system on it- I’d buy more of them.
