I bought this same exact filter 14 years ago. With regular cleaning, I never had any functional issues aside from the bio-wheel just getting gross and needing to be tossed around the 10-year mark.The only reason I needed to replace this filter is because it started to make a low noise that started to freak out my fish (they had recently been transferred from a different tank also with a newer Marineland filter). The old one was still working like the day I first set it up aside from a bit of noise.Great price for how long they last. I'm pretty sure I paid the same price 14 years ago.The filter cartridges are super easy to install and pretty inexpensive and I've managed to find them at just about every pet store I've ever been to.

Clicking/vibration noise coming from the filter. Have tried resolving with the help of youtube but nothing works. Can only assume that i have faulty goods.Returning this item back to the US is not cost affective so my fault for purchasing in the first place.

This has been a great filter. That said - I’ve just set my tank up and have been cycling. It can be noisy - but only if you don’t have your tank filled up. As such it wouldn’t be suitable for half water tanks, reptiles, etc unless you enjoy the noise. Great value!

I have been using these power filters for almost 17 years. We have had several tanks. Recently bought two for my new 80 gallon shark tank. We now have the four bio wheels (which by the way are not supposed to spin all the time which means they’re working and you’re doing something right) and four bays to put extra media in if required. These systems are hardy and reliable. If you’re doing weekly water changes, rinse out to eliminate any algae/slime. The system gets louder as the water level evaporates.Always rinse charcoal media before placing in bay.I’d recommend this product and indeed all Marineland products. I don’t buy any other brand with as much confidence.

So I had some trouble when I first installed my filter, and I figured I would share the steps I went through to fix it in case it helps anyone else.I put everything together just like the diagram but when I plugged it in, all it made was this really loud grinding sound and there was no water flow. I opened the lid and I could see some bubbles but nothing obviously wrong. I pulled stuff apart and checked the propeller and couldn’t see anything wrong there either. I had set up everything in order according to the directions and was baffled.I began trouble-shooting. When I called the help hotline (it was outside business hours so I couldn’t get a person), something they suggested is taking the propeller out and with the filter plugged in, hold it up against the outside of the filter. If you can feel the magnetic tug, then at least the motor is working. So I pulled mine out and tried this. Propeller and motor were good.Another review mentioned trouble with the flow lever on the intake tube, so I fiddled with this. No change. But it did give me an idea since I had seen bubbles, I figured it could be a different problem with the intake tube. Long story short, the three sections of the tube weren’t connected as tightly as they could have been. Tightened, water started flowing through the filter. There was still a bit of noise, but I noticed that my tank was filled below the top connection point on the tube. I added more water to the tank until it was above the line, and presto, no grinding noise!So if you do have problems with flow or noise you might check your intake tube and make sure it is tightly together (REALLY tight) and maybe fill the tank above the top connection.The filter itself seems to be working great. The water flowing back into the tank can be a bit loud, but it isn’t nearly as bad as some filters I’ve used previously. I really like how sturdy it is built and that I can insert two filters back to back for more filtration if I like. Also, the cover is super easy to take on and off. The bio wheel sounds neat in theory but it isn’t even spinning in mine. Not sure how to fix that or if it really matters. Maybe I’ll fiddle with it later.The fish tank is in the bottom of my Chinese water dragon vivarium, so as you can imagine it can get a bit messy, but the water has stayed clear and clean, so I’m please enough.Update: So it has been running for about a month with no problems. I got the biowheel to run for a bit, opening the flow more on the intake tube and pushing the wheel back all the way in its housing. The water has stayed pristine even with my lizard so I’m really happy with it!
