  • waste of money
    Had this a year and it was not would lose prime and was a pain to get working again after cleaning. It was also VERY noisy! Bought a self prime canister filter instead....more info
  • Excellent filter
    I have a 75 gallon tank with an emporer 400 filter. It just didnt seem to be able to keep up with the fish I had. I added this filter in, and within a couple days the tank was amazingly clean. This filter is great, in that it has an optional vent midway up on the intake. I was skeptical at first, but after seeing this work I will support this 100%. ...more info

    Does a great job of filtering but it is noisy. Wish I would have bought the Emperor 400 instead. ...more info
  • Most Amazing Filter I Own
    this is an Amazing filter. the bio wheel does a great job at polishing the water... i can even say, this filter works better than the Magnum 350, mostly because it needs less cleaning...more info
  • Seek filtration elsewhere.

    I have had my Penguin 350 Bio-wheel just over a year now. I purchased a different brand of power filter to replace it this morning.

    After about three months the filter motor began making a constant and irritating grinding sound. I had performed monthly cleaning of all the filter parts before this, and when the grinding began I cleaned it thoroughly again. It made no difference and the grinding continued.

    Strangely enough a month or two later the grinding stopped for a few weeks. I rediscovered the beauty of a quiet living room. Not for long, because inexplicably a few weeks later the noise began again. So instead of paying Penguin $14 through their website to purchase a new impeller assembly (which probably wouldn't fix the grinding anyway since my impeller shows no sign of damage) I decided to purchase a new Aquaclear filter instead. That is what the owner of my local fish store recommended in the first place, but I bought the Penguin in order to save a few bucks. Whoops. I hope someone out there learns from my mistake.

  • Works well, Easy to clean
    I've had this product for almost 1 year and it is still running. I clean it by hand once every six months. The filters are easy to replace, and so are the bio-wheels if you ever really needed to replace them. Comes with an extension extra that is not the most needed thing ever but is very helpful if you actually do need it....more info
  • Only one drawback...
    I have a 55 gallon community tank with angels, pleco's, clown loaches, and cory cats. Some messy fish, but this filter carries the load. My only recommendation is to clean the intake tube with each water change. It gets pretty gunked up, very easily....more info
