  • Love it! wonderful, especially for the price!
Size: 30 - 50 Gallon Aquarium, 200 GPH Pattern Name: Filter
I am now running this filter and a sponge filter in my tank ever since my last filter gave up. This filter is NOT as loud as the reviews make it out to be. I have a 36 gallon tank and it’s in my bedroom. As long as you keep the tank filled, which you should anyway, it is not loud at all.. Just like any other filter, if it does get loud and your tank is fully filled, checking the filter for debris and it will solve the issue. I sleep with it running every night.. (Side note: I have ADHD so sometimes noises really bother me at night and keep me up, but this filter does not!) I have had this for months by now and I have never had a problem with it. The bio wheel does wonders. Between this and my sponge filter, my water stays clear. I am sure this filter could handle the tank all on its own, but after my top fin filter completely gave out after 6 months, I was left without a filter for at least a couple days. Running two filter gives me reassure and extra filtration. Overall, this filter is wonderful, I highly recommend it. ... show more

  • Works great after some troubleshooting!
Size: 30 - 50 Gallon Aquarium, 200 GPH Pattern Name: Filter
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! ... show more

  • Penguin 350 for 29 gallon tank
Size: 50 - 75 Gallon Aquarium, 350 GPH Pattern Name: Filter
I have the topfin 29 gallon tank and used the HOB filter it came with. I wasn't satisfied with the filter because it stopped working great after about a month, even when I cleaned the specified areas. It wasn't producing much surface agitation. I was also having oxygen issues because of this. I wasn't able to fill my tank fully because there was little to no surface agitation. I had to lower the surface by 3 inches to get sufficient agitation. This was annoying because it sounded like a leaky toilet and I wanted to fill my tank more. SO I decided to order this for my 29 gallon tank. I researched if it would filter my tank "too much".. apparently there isnt such thing. From what I learned, i needed to add a zero to my tank volume and that's how many gallons per hour the filter should be producing. So I needed 290 GPH and the 200 model wasn't going to be strong enough, so I opted for the 350 model. This filter is perfect!!! It is pretty big and I was surprised when I opened the box it came in but it fits perfectly on the set up I have. The current is strong but you can adjust it with the midsection lever. My fish were a little perturbed at first, but they seem to love the current now; they ride the bubbles and relax right under the current. There is a sound from the water shooting into the tank!! I dont mind this noise because, to me, it sounds like rain trickling or a small waterfall. Doing research I learned that if I add more filter media, the noise will subside. Unlike my old HOB filter, it doesn't sound like a leaky toilet. Good news: the actual unit does not make any grinding noises. Remember if you are replacing an old, cycled filter, you must run the new filter with the old one for at least 2 weeks. Since the filter is the heart of the tank, you want to make sure the beneficial bacteria has time to colonize in the new filter. The penguin 350 has plenty of room for extra filter media, so you could also add the old filter media straight into this model. Therefore, you wouldnt have 2 filters running. Just a tip! Overall, I'm very happy with this filter. I can't wait to experiment with different filter media and optimize the functionality of the penguin 350. Definitely recommend!!! ... show more
