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

This hob is great! My original (not this brand) started leaking after several years so I had to get a new one. Not sure if there have been advances in tech but this works just as beautifully, completely silent and I am VERY happy with how this works, looks and sounds. Highly recommend! I am considering adding more to my other tanks as secondary filters…

I love this filter. It's kinda loud but I don't mind cause it gets the job done perfectly. Only issue I had is the filter cartridge it came with constantly caused the water level to rise which the light indicator showed but a different filter cartridge and you're set!

Very good filter. The media compartment is a little small, I can’t add extra media as I like to do with my HOB filters. But it performs nicely, is quiet and it’s nice to be able to adjust the flow for the size of the tank. It’s not self-priming, you have to fill it with water before turning it on. Big deal. I’m used to doing that with all of my filters. Filters that are self-priming have the motor and impeller sitting in front under the water. They also have a “minimum” water level indicated. If you like to leave a few inches clear at the top of the tank, that’s no good. Also, it makes it a pain to clean the impeller. I do recommend this filter and the price is right.

Hygger is a good reputable company that makes quality products. I have bought several pump filters and heaters etc from them and never been disappointed. This filter is quiet and as powerful as you need it with adjustments to lower or raise the flow adequately. It's easy to take apart to clean and really had no real assembly required out of the box. It came quickly and is a great pump

Looked big and impressive, but the aquarium-0nly a 20 gallon one-remains cloudy-and it’s supposed to clean an aquarium twice the size! I over-bought because the 20-30 gallon filter didn’t do the job!

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

I got the Large for its small in depth (tank to wall) but this has caused damage to our floor because the water overflows when the filters are full. Yes there’s a red light but when you’re asleep you won’t notice. I feel that the filter material is too dense. Even without filter, the plastic mesh can stop the flow. I can’t let it run without changing filter every other day. I have another one, same model, that works as it should.

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.
