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 pump is very powerful. A little too powerful for my 40 gallon tank. But it keeps the tank clean and clear. The fish usually avoid that side of the tank, unless they’re feeling like a joy ride. Every now and then they have fun playing in the powerful water output. They swim into it, which sends them flying and then swim back and go for another ride. It also shoots my live plants around, which I don’t love. I plan to try to diffuse the water output and see if I can aim it to cause less stress on my plants. I will likely add it to my 75 gallon tank in the future and get something a little less powerful for my 40 gallon. But for now it’s doing its job.

It works awesome. Too awesome for my 40 gallon pond. The product listing says 40-150 gallon. It’s waaaay to powerful for anything under 75 gallons. The water movement is too great for the fish and they suffer as a result. This unit needs a ton of water space then add lots of decora or rocks situated in house shapes to make hidey holes the fish can go in when they need a break. The jet is powerful and it moves the water too well. The problem is you can only turn the flow down to a set amount which was still too much for my pond. It’s really perfect for an extra large setup though and I can totally recommend it for that. The filters are mega and the filtration system kicks major butt. It has two monster filters that easy to remove, wash clean and put back in. It is a really great thing…..for a large set up only. In my case, I have to return it but as a lifelong fish tank owner, I can say it’s a fantastic product. So winner winner chicken dinner if you have a very large setup and need a system to accommodate it. For smaller setups, keep looking.

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!!
