NICREW Aquarium Internal Filter, Submersible Power Filter with Adjustable Waterflow, Aeration System with Sponge Filter for Fish Tanks 10-20 Gallon, 100 GPH, 7W

I was unsure at first because it wasn’t a name brand. However, I am glad I didn’t sway me away because after several years this filter is still reliable. I upgraded my filter size from the MiniMagi to this one because I just have a lot in my tank right now. It’s easy to clean and isn’t loud. I also love that it’s not bulky and fits entirely in the tank. There is also no way for a fish to get stuck inside the filter which is great.

This filter is working nicely as expected from NICREW

Update: I gave up on this. It gets clogged up so easily, I was having to clean it every day or it would stop working right. I've got 8 tanks, I'm not inexperienced but I struggled to make this filter work correctly. I went back to a sponge filter and my tank is so clear now! I should have kept it running instead of this filter.________I've never had so much trouble with a filter before. I was using an internal sponge filter and switched to this filter because the tank is in my bedroom and the bubbling was annoying.The pieces aren't great. I wanted an elbow piece to attach to the spray bar so the spray bar was vertical with the filter but the pieces don't fit together to make this. *Edit: if you use enough elbow pieces you can do this but the spray bar is very longI keep having to clean this filter out, things keep getting stuck to the slits on the side where it pulls in water. You would think that's a good thing but it blocks the filter and then the air tube and regulator stops working and doesn't produce bubbles anymore.If you have the air tube and regulator on it helps to turn the tubing inlet so it is horizontal, it seems to keep the water from going into the tubing, th water stops air from coming out when this happens. It's also very loud. I don't know if it's the regulator that is bad or what but the bubbles are really fine and they crackle as they come out. You can close the regulator almost all the way and it is still loud, sometimes it sends the air out in short loud bursts.Ramshorn snails keep getting stuck in the part of the filter where different arts connect, they are getting their bodies stuck in crevices then they can't get back out and they die. I learned this the hard way when I went to pull one off the filter and I pulled it's insides out of its shell.As of right now I definitely wouldn't recommend this filter

Had this about 3 years and today it shocked the hell out of my hand while I was doing a water change. No strain relief where the wire goes into the motor at the top and the plastic on the wires evidently dried up and cracked. Never had something like this happen before. Up until it became a hazard it worked well except for the suction cups which would not stay attached.

I am very happy with this filter system. It’s very quiet. I enjoy the fact that you can move the bubble arm to the side of the tank or to the back of the tank. It is a very quiet filter system.
