Rated 1 out of 5 by from Bio-wheel may not work I bought this product 2 months ago From Marineland. At first they work like a dream, but then start reducing in cleaning power after a filter change and the bio wheel doesn't spin after a month. What is this Marineland. Overall very disappointed with the product. Contacted Support Team and they say it's an issue with my power. How helpful.

Rated 5 out of 5 by from Awesome filters I've got several of the Penguin filters on my tanks. They always perform superbly. All the problems I see people post about are either a genuine failure, they do happen and Marineland will take care of it, or improper care and cleaning. I've never had any problems out of mine though. Just like anything else, keep it clean and it'll keep you happy.

Rated 1 out of 5 by from Disappointed I’ve bought 4 different sizes for all my fish tanks and after several months the biowheel stop spinning and started making loud noises. I’ve called the customer care and the representative was not helpful and told me I’f I’m not happy I should buy a different brand filter. So here I am shopping for a new brand filter.

Rated 5 out of 5 by from Awesome! Not seeing a whole lot of difference between this and my Penguin PF99 from the late 1990’s. Still the same quality! Great filters!

Rated 5 out of 5 by from Bio Wheel One of A Kind I have used Marineland Penquin Power filters for many years now and they are an excellent HOB filter. The bio wheels work effectively to deplete the water of gases and introduce oxygen back into the water. And with the bigger models there is room for two cartridges or room to put your own media in the box for different filter needs. They are very quiet when running and are quality made with solid components. I would recommend them to any seasoned hobbyist or beginner alike.

Rated 1 out of 5 by from FAILED WITH IN 24 HRS We just purchased a Marineland Tank combo that included this filter yesterday and this morning the filter is dead, does nothing. Very disappointing to say the least as we have always had great experiences with Marineland products. Hopefully we can exchange this without having to bring the whole tank back.

Does the Penguin filter range run off 220Vac also, or only designed for 110Vac?

Asked by: ianrwood
It is designed for 110V only. You could use a converter perhaps. BREX

I am upgrading from a10 gallon aquarium kit to a 37 gallon marineland tank and stand the new tank does not come with a filter. Can In use the penguin from the marineland 10 gallon kit and add a second filter?

Asked by: Jrc55011
You can use it, yes, but it won't filter much. It's main purpose will be to help seed the new tank with good bacteria. Other than that, there really isn't much point to use such a small filter on that size tank. I would run it for a week or two while the tank is cycling, then remove it. You need something like a Penguin 200 for proper filtration. BREX

Hey , I cleaned my bio wheel and tank now it is running loud. Can anyone help m out?

Asked by: Butcher
Well, when you cleaned it did you remove the impeller from the bottom of the filter box? Noise typically comes from something being caught in the impeller or motor region. It can also occur if the intake tube is not seated correctly or if there is an air stone near the intake tube. Sand getting caught in the impeller will cause grinding noises. So basically, it is always a good idea to remove the intake tube, impeller housing and impeller, inspect and if necessary, clean them. Also inspect the motor region as well. BREX

For a 30 gallon aquarium is a Penguin 150 or 200 advisable? I don’t want to potentially get a strong one that will be splatter water all over.

Asked by: Karim117
That depends on the tank's needs, basically. The Penguin 150 is rated for tanks up to 30 gallons so you would be maxing that filter out, depending on the type of fish you are keeping. The Penguin 200 is not overkill and is often used in that size tank, especially for goldfish and cichlids which are particularly dirty fish. Neither filter will splatter water any more than any other filter, but we do recommend floating the biowheel for the first day or so to help it to absorb water and eliminate noise in new filter systems.

Bio doesn't spin. Water flows back next to the intake tube. Water level is high enough. What's the problem?

Asked by: Scotteh
Same with mine. No obstructions, water is high enough in box and in tank, everything is good but it doesn't want to spin.

I have a 150 and a 350 the 150 seems to be moving a lot more water than 350 what do you think the problem might be the 350 is brand new

Asked by: mumblypeg
Well, since the motor and the impeller on the 350 is much larger, that certainly isn't possible. Also, the flow is split between two chambers so keep that in mind. Some possible causes can be clogged cartridges, low water level in the tank, or if you added additional media, this would slow it down too. Also, even with a brand new filter you can pull something into it that may interfere with the impeller. Check it for plant matter, sand, grit, carbon dust, and so forth. BREX

Hi i love live in Barbados and I have the filter but there are no cartridges available what can I do since there is none. Another question is that my water in the tank still isn't keeping clear what might be the problem i have 150 filter

Asked by: Trinity27
As we do not export our products, we cannot advise on how to purchase our products outside the U.S. In regards to the cloudy water, that could be due to any number of possible causes. New Tank Syndrome, adding fish too fast, too many fish for the tank, over feeding, microscopic animals such as heterotrophic bacteria, water changes not frequent enough or too frequent, and so forth. Without any information on your tank, we would recommend testing the water quality, vacuuming the gravel and changing out 25% of the water. We would also recommend adding a bacterial supplement like our Bio Spira. BREX

I purchased a 200 model for my 50 gal tank does it matter that the intake pipe only goes 2/3 rds of the depth or the water?

Asked by: Jsmall
No, not at all. Anywhere between 1/2 and 3/4 of the way down is recommended. BREX
