Not Working - Used Product

I don't have any aquatic animals. I don't have a water feature. I do have 3 medium sized dogs, and this filter has been absolutely fabulous!I had bought pet water fountains for my dogs. I had to have 2 big ones because you have to wash them ALL THE TIME. Like the water under the lid gets nasty within 4 days, when you have 3 dogs. It was awful, but they loves drinking out of a fountain. One week, the filter cover broke on onw fountain. Another week the pump broke. Not wanting to pay $65 (on sale) I looked to YouTube.So, for the fountain that has a broken filter cover, I just didn't put a filter in. I didn't have the proper hose to fit this aquarium pump to the fountain spout, so I used the working pump to cycle the water to the top, for now. It has been 15 days. The water under the lid is STILL CLEAN!!! I have only addes water until today. Today, I had to clean the lid/cover because that water never tickles down below so the filter can clean it.Bonuses for using the aquarium filter as a pet water fountain cleaner: the water is actually clean, you do not have to change the filter every 4 days, the filter nor the water stink after 4 days, less cleaning to do (I will clean it all for maintenance, but not quite yet), inexpensive compared to a new pump and more filters (pet filters are 2 per week and $1 to $2 each, lest you have dirtier water).Cons, if you get the one for a 20+ gallon tank or whatever, it will be LOUD, but it does the job really well. If you turn off the air hose, it is less loud.This can also work in just a large, deep, pan for pet water, too, but my animals wouldn't drink out of it until I put the lid back on and made the water come out of the spout. (Ridiculous)For a pet water fountain, I have this in my smallest one, which is a 12 liter fountain. I will switch it over to the 16 liter pet fountain, and get the proper hosing, so this filter is filtering AND pumping.For perspective, a new pump can be $15 to $20, for a pet fountain and does not do as good of a job. Plus $20 for 10 to 12 filters that you have to replace every 4 days or so. I did not need the size of water filter I got, but I wanted to be extra sure the water stayed clean. I have not had to change the filter for 2 weeks, nor clean the fountain other than wiping the top. It looks like the filters for this filter last a LOT longer, too. Not sure when I will have to replace the filter, but it probably won't be for at least 3 months, with how well this is doing.

This thing is a powerhouse. It gets the job DONE. Taking it apart to service it is incredibly easy, too. Yes, it's a bit loud but with how much water it moves that's not surprising. And at this price I think it's well worth it, it's an absolute beast!!

Holy smokes, for once the advertised flow rate was legitimate, insane power. This has got to be the best bang for your buck in terms of flow rate and filtration capability.Do not put this in a 40 gal unless youre trying to simulate white water rapids, the flow rate is not adjustable.Love this thing.

I was using this for a 30 gallon. A bit too strong for this size but i figured a way to calm down the current for my fish. I love not having to buy new filters. Just wash these out. My only con is how the top part comes off and you have to becareful because when you take it apart the middle where the pin rod and motor is kind of falls apart and you dont want to lose anything. When you try to turn the top where the water flow comes out,you can only move it so much otherwise it unlockes it and comes off. I wish there was a way to lock it and still be able to turn the out going flow with out that worry. Like it should be seperate pieces. It is a great pump though.
