Rated 4 out of 5 by from Cleans well I bought this filter about a year and a half ago. I have really liked it until recently. The propeller has gotten really loud. I have tried cleaning it, oiling it, only helps for 10 min. Any suggestions?

Rated 4 out of 5 by from Great Filter !!! I have had a Penguin 200 for over 10 years now and my water is crystal clear. It's been in my 30 gal. tank and now it's in my 55 gallon. if you clean and do your regular mantance to the filter it will give you many years of clear water. Ordering parts are easy and quick it doesn't get any better than that Thank You Marineland .

Rated 4 out of 5 by from Filter? Bio filter 75 doesn’t seem to want to spin? Not sure if that is normal.

Rated 5 out of 5 by from Wow What a Difference I had an aquarium when I was a teenager, and even with several plant-eating fish and a north facing window, algae was always out of control. We bought our first Penguin filter a year ago as part of a kit that was on sale for 50% because of the price and complete kit, and we were happy to find what a difference the biowheel makes in overall aquarium cleanliness. No more out of control algae. There was a little, but nothing a scrubber and a low dose of algaecide didn't take care of. Water clarity is crystal. Our fish look very happy, and so do we.

Had a penguin 75 that stopped working, bought a penguin 100 ( the bio wheel is bigger), where can I put the old bio wheel so it keeps helping with the biological filtration ( since is too small for the new filter)?

Asked by: Vigomateu
Did you try cleaning the impeller and motor of the 75? If this is all it needs, you can run the two filters simultaneously for a couple of weeks. If the 75 is clean but dead, then you can float the bio wheel if it isn't too grungy. BREX

How do you adjust the mid-level strainer? Is that the gray fan-like thing in the middle? Can you give more detail regarding that? There isn't any instructions or details about it in the pamphlet. Thanks!

Asked by: plii
Yes, that would be the mid-level strainer. If you leave it open it increases your flow rate, closing it reduces the flow slightly, and prevents you from pulling water from the middle of the tank. BREX

I purchased the marineland penguin 200 from PetSmart and when I got it home the biowheel was not in the box. Was it supposed to come with the biowheel or do you have to purchase it separately?

Asked by: Melissad
It definitely should come with the bio wheel so please call our Care Team at 1-800-322-1266. BREX

Is there a way to lessen the flow rate so it generates less bubbles? 

Asked by: Plii
The power filter does not generate bubbles, unless the water level in the tank is below the filter's spillway. If so, raise the water level. The only way to adjust the flow is to close the mid-level strainer (gray lever). BREX
