hygger Aquarium HOB Filter 315 GPH for 40-75 Gallon Fish Tank Power Filter with Adjustable Water Flow Extendable Intake Tube External Hang-On Back Filter

Seems to be a solid filter and high powered for the price. Even at a lowest level the filter is pretty strong so I did end up installing a buffer for my small fish and shrimp but it works great and I’m always impressed with how much it cleans the water.

It is pretty quiet compared to my other filter, it’s almost silent. It’s been keeping my tank crystal clear. I wouldn’t use it for smaller than 10 gal. The flow knob has good control. It’s gentle enough to keep shrimp or guppies. I’ve had it for about two weeks and so far it’s been going strong It comes with just one filter cartridge And it clears my floating plant’s roots. Which are an eye sore and now they’re gone! Cleared my tank in about two days

As described and really does a good job and very easy to clean and also easy to change the filter and truly loves the fact that it tells you when the filter needs to be changed.

Do not get this. It sucks air really bad and sprays bubbles. I usually love hygger but this filter model is just horrible. Not only did it suck air into the intake, it was the most awful sounding filter I ever had. It also did a bad job of filtering my water so it was always cloudy. I finally got rid of this and replaced it with an aquean clear 50g. My tank now lives happily ever after.

Love how quiet it is but the water flow doesn't adjust lower like it should

Recently installed the Hygger HOB filter onto my 125 gallon aquarium in conjunction with my Flugal FX6 Cannister filter to maintain crystal clear water, as well as, healthy environment for my fresh water fish. Easy to install and adjust water flow. Be sure to keep replacement filtration pads on hand as this does a great job removing unwanted "solids" from the water!

I wish i could lower the flow even more I feel like the flow is the same no matter what setting it’s on so I don’t even run it since I have guppy fry and shrimp as well as floating plants. I will say from the little time I did run it, it was very quiet even though it was against a wall

I have had my own aquarium business as well as worked as a Manager and Distruct Manager of several pet stores through the years, not to mention being in the hobby for 50yrs. I have seen and sold every HOB filter that was manufactured. This filter beats them all. I will say that I still use the AC bio sponges and bio media for the back of the filters to get more bio surface area. This filter is much more narrow than others, so the sponge just needs to be turned sideways and the ceramic media fits right on top of the sponge as well. The filter has to be filled with water before attaching the impeller mechanism or it won’t prime properly. Otherwise, it will be very noisy. These filters are quiet, and I like that there is a corse sponge to attach to the end of the tube. This is not only great for more bio surface, but especially useful for anyone raising fry, shrimp, snails, or nano fish. Excellent filters, will be purchasing these instead of whisper, AC, Penguin, or any other HOB filter that hasn’t made the cut.

Recibí el filtro el 11 de enero 2025, al día de hoy ya no funciona, resulta que se fue la luz por unos minutos y ahora ya no prende. Deje enfriar el motor varias horas y nada. Estaba muy contento porque funcionaba muy bien y mantenía cristalino mi pecera. Pero por un apagón no puedo creer que dejara de funcionar.
