Rated 1 out of 5 by from Worst filter I've ever owned! These filters are garbage! I've had a couple filter for months. They constantly makes a grinding noise since I've had it. I've even taking it apart and put it back together multiple times to try and fix it. I've read this is very common in these filters. Stay away and go with an aquaclear .

Rated 5 out of 5 by from Great Quiet filter I bought a 10 gallon Marineland with a Penguin 75 filter about six months ago. It was to replace a smaller tank. I love the easy set up and the waterfall filter. It has been working out great.

Rated 3 out of 5 by from They work great but... I have two (1) is a 150 and (2nd) is a 350. Impellers in both have gotten loud. My 350 came with a damaged rubber grommet on one end but didn't notice it till a month after i bought it. Now i'm looking for new impellers after only 6 months. Thats proving to be a challenge as well!

Rated 5 out of 5 by from Multifaceted Filtration For Clear, Clean Water. I recently bought the Penquin 150 Bio Wheel Filter. It is a well built system that oxgenates the water thoroughly. There is room for 2 filters and other biomaterials. The rotating wheel for added biofiltration is a nice touch. It is also a fairly quiet unit. The only drawback is the outflow current is pretty strong. My fish can deal with it, but if you have a planted aquarium, you may want to move your plants about 4 inches or more from the outflow, as I did. I also have rocks and plants setup so my fish have a quiet spot to retreat to. The strength of this filter, however, makes for good water circulation.

Do you need to replace the bio-wheel after a case of Ick?? Or should it be okay if it has been drying for several weeks?

I installed a penguin power filter 75 on my ten gallon,the filter does nothing but make a faint buzz.I filled the water level to the top of the tank.Thank you for your help.

Asked by: Charlotte34565578
Pull out the impeller and impeller housing as well as the intake tube. Make sure you have the filter filled up with water too, and then re-seat these parts. The tube should fit pretty snugly. If you still cannot get it to operate, call 1-800-526-0650. BREX

I purchased two Penguin Power Filters(up to 20 gallon) from amazon on 7/5/2018. My order number is 113-0996277-4789857. The bio wheel not/harder spin. Why?

Asked by: Yunqi
Make sure the water level in the tank is all the way up to the top of the tank, as water level affects the filter flow which in turn affects the bio wheel. Remove the impeller, and clean it, as well as the motor in case of debris, and check to be sure the bio wheel bearings are properly in place, and clean. BREX

Can I use my Marineland Penguin filter outdoors?

Asked by: Sully47
It is not rated for outdoor use, no. If you are placing a tank on a carport or enclosed porch, etc., and it won't be rained on, it should be fine for that purpose. BREX

my bio wheel is not turning I looked and seen it has a 2 inch rip in the paper part is that why its not turning should I replace

Asked by: keesha1994
Yes, that is probably why it isn't turning, although you may also want to clean the impeller and motor as well. The bio wheel is directly affected by the water flow rate, so if the filter has a build up of sludge, algae or other deposits, this could be the issue. BREX

My penguin 150 has algae in it. It’s in a 33 gal w Neon, Platy, Loach, shrimp, and 2 dwarf Plecos. There is no algae visible in the tank, water is clear. It’s been cycled for 1yr. I feed 1x / day and regular maintenance. What should I do? Thanks.

Asked by: Grad
Your filter requires maintenance periodically, just like the tank, or your car. Every 2 or 3 months, you take it off, take it apart, and clean all of the various parts, other than the bio wheel. Use warm water, an aquarium wire brush, soft cloth, and if you need to, white vinegar. BREX

My emperor is not pulling water through the biowheel spray bar. It is three months old. I’ve cleaned the intake, propellor, and spray bars with the pipe cleaners provided to no avail. The filter is noisy and send extra bubbles into the tank. Thoughts? Thx

Asked by: nlee
The only thing that causes water to not move through the spray bar is a missing flow manifold housing cover, or one that is down in the motor but not snapped onto the bottom of the flow manifold housing. Extra bubbles makes me wonder if the water level in the tank is low or if there is an air stone near the filter. BREX

When I change out the filter cartridge on my Penguin Bio Wheel, white particles get released into my tank right before I put the new cartridge in. Any idea what this is about?

Asked by: jmac
It could be any number of things, all of which indicate you need to take the filter system out, and apart, for cleaning. Regular maintenance is recommended every 2-4 months. BREX
