hygger Hang-On-Back Canister Aquarium Filter,No Dry Burning Quiet Fish Tank Filter with Duckbill Nozzle Shower Pipe Outlet Oil Skimmer Adjustable Water Flow 3 Types Filter Media (8W for 40-60 Gal)

My initial post was very positive, based on out of the box functionality and adaptability. While I still find the functions great, unfortunately the pump stopped working after only a few weeks. I did have the same micro bubble issue I read in other posts. I narrowed it down to the top not getting fully seated to the bottom. I suspect the O-ring is not adequate in size to create the air tight enclosure.This product is a great concept, but bottom line if it only works for a few weeks, its a waste of money.

This filter pump is very quiet and moves a lot of water. I like that the filter media is not proprietary, like some other popular brands; you can buy it virtually anywhere if you ever need to replace it.I currently have it on a 10-gallon aquarium. I figure that it is easier to dial back the flow rate than to replace the pump if more is needed.All in all, I feel confident that this is a high-quality unit and is worthy of your consideration.

I bought 2 of these. One still works. The other quit working after 2 weeks. Nothing you can do to get rid of the air bubbles my guess as to why the pump burnt up. The internal design needs redesigned. I spent alot of time making sure that seals were aligned and everything was tight. The surface skimmer needs an engineer to get it lined up straight so it works. Now that being said, the one that still works does an awesome job and has no air bubbles coming out of the spraybar its really quiet and keeps the tank water well circulated. My guess I got one that had bad seals or piping out of tolerance. Like other reviews stated air bubbles are a problem.

Very happy with the overall function but the orings for the flow adjusters aren't sealing fully and every now and then it sucks air causes it to slow down in functionality and sends filter debris back into the tank other then that I very much love the over ascetic and performance but I'm sure I can get a oring somewhere to seal it right

It's was great while it was functioning but motor got very hot and stop working today. I received it Nov 30th. Wish the life on it was longer.

The concept of a HOB canister is great. This filter nearly got it perfect. It’s quiet, powerful, and adjustable. It needs a couple of things:1) The option to NOT use the skimmer. Luckily I had a rubber stopper that was the correct size to plug up the skimmer tube opening. It should just have an optional tube that lets you just use the main intake.2) The sponge that covers the main intake needs to be better. The one provided is pretty thin and may not prevent shrimp and fry from getting sucked into the filter. Luckily I was able to use a better intake sponge from another Hyger HOB filter.3) the filter, clogged up very quickly and is not easy to remove disassemble and clean without taking the entire filter out of the aquarium and pull it apart.My update is that I’m replacing this filter with a hang on back with a removable basket.

**1.0 out of 5 stars – Disappointed and Out $40**I purchased this filter for my tank, and it was a complete letdown. It lasted less than 48 hours before it stopped working entirely—no movement, no sound, nothing. While it was working, it kept belching bubbles every hour or so, and then it quit as if it had no power. The internal design is flawed, with air bubbles likely causing the pump to fail.I also spent a significant amount of time ensuring seals were aligned and everything was tight, but it didn’t help. Customer service was unhelpful and dismissive, blaming user error despite clear video evidence of proper installation. Their response was condescending, suggesting I “make sure there’s water in the tank.”This product feels poorly engineered, and while some units may work (based on other reviews), mine was a complete waste of money. At $40, I expected much better reliability. I won’t be buying from this company again.

The media could not be loaded. *update* I love this style of hob! It's quiet, adjustable and doesn't take up as much room in or outside of my tank. Thank you! Love it and will be getting one for my other tanks too.Takes a couple to put together but it's quiet and efficient! Love that I can control flow on intake and output ☺️ Ty!
