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.

Rated 5 out of 5 by from Works well, reliable, and customizable. I started being deployed for combat frequently at high tempo, so I gave away my fish and let my parents keep my tank and equipment until I was ready. My old 20H setup sat empty in my Dad's garage (in Iowa) for TEN YEARS. I just got all that stuff back and set it up to see what I need to purchase. I cleaned the Penguin Power Filter housing, held the pump section under running sink water, and nudged the turbine with a chopstick to get it moving again. The pump turned on and everything works like new!RELIABLE... mine was used with heavy load tank for two years, sat in the elements for ten years, and is now being used again. It still functions great after a decade!CUSTOMIZABLE... there is space in between the filter and Biowheel to put other media such as SeaChem Purigen bag or CNZ ceramic rings.WORKS WELL AS A SCIMMER... I use both my Penguin filter system and an AAP Hydro Sponge filter in my tank with excellent results.LOUD (and QUIET)... the "waterfall" is super loud; however, if you get the water outlet at or below water level, it is SUPER QUIET! I added an extension to the outflow "ramp" in order to achieve quietness, (again, easily customizable). If you keep the waterfall the way it is, the Penguin agitates the surface and oxygenates your water very well.COST... replacement parts can be very expensive! If you shop around, you can find filters for a cheap price; but, the biowheel costs almost as much as a new entire unit! I change the filter cartridge monthly, and am going to continue using the original Biowheel.For a Hang-On-Back power filter, I definately recommend the Penguin series! I will purchase again for sure! I love how well it works as a scimmer, and how customizable it is. It is super loud... unless you customize or modify it for your needs (or keep your water level topped off in the tank).

A friend gave me a Penguin200 w an established Biowheel for a 27 gal tank. It creates huge current, looks like the 200 is made for much larger tanks. Thinking about switching to 150, but can i use 200 biowheel or would i have to start over?

Asked by: Audlindal
The 200 model is for tanks 20-40 gallons in size, so should be fine for your tank unless you have some pretty small, delicate fish. You would need a different bio wheel for the 150 and would not be able to use the one with the 200, unfortunately. BREX

I have a 100B on my 5G hex tank. It's great, keeps our water clean and I finally got my tank to cycle. However, the outflow is too turbulent, even with a full tank. Can I adjust it or modify it in some way?

Asked by: FireworksMom
Closing the mid-level strainer off may help some, but ideally, you should place some filter floss inside the strainer. This will slow it down or you can put a second cartridge in the filter which will provide more filtration and slow it down. Another option would be to add some other bio media in the main chamber.

I have a Penguin 150 in my Mainland 20 gallon tank. No issues! But I do have a question. Why is there a spillway located to the right of the bio-wheel? That is unfiltered water...right? Seems all water should be filtered. 

Asked by: Jeff1320
Yep...your right! took it apart and cleaned it all up and works perfect now.  Now...I changed about 1/3rd of the water last night. Added ReadiStart and AccuClear as normal. 8 fish dead. Never had this happen before. I’m taking a water sample to the fish store now. Test strip did not indicate any problems.

I Have a Penguin 350 That I've Been Using For About a Year. I Took My Aquarium Down as I Was Relocating to a New State. Tonight I Set Everything Back Up & My 350 Will Not Take in Water. I've Tried Everything

Asked by: Hoffa
Sorry to hear that Hoffa! So make sure the tank is filled to the top with water, and the filter box is also filled with water. If they are, then I suspect your impeller has separated. It will do this sometimes when kept dry in storage. To inspect it, hold the top and bottom tips between the thumb and index finger of one hand. Take the other hand and flick the blades. The blades should catch the magnet within half a turn and they should rotate together. If not, it is separated. If you need more help, call 1-800-322-1266. BREX

Is it helpful to any other filtering media in the housing? Ceramic pellets? Whatever?

Asked by: Bill1222
Yes, of course. It is always helpful to have additional media such as ceramic rings, bio beads, filter floss, phosphate pads, etc. BREX

installed my new penguin bio wheel filter, it seems to be working fine with the exception of the actual wheel which is not turning. any suggestions

Asked by: alandjanice
Make sure your water level in the tank is to the top of the tank. Also, check the purple bearings at each end of the bio wheel. Make sure they are properly in place, and clean. You might want to rub a bit of silicone lube on them. If they are missing, call 1-800-322-1266. BREX

I have the canister filter and doing my tank from scratch, so I dont have water from a aquarium to rinse the media with. What to do?????

Asked by: Michelle3251
Rinse it out with tap water. If everything is brand new, it doesn't really matter. It's just if you are cleaning the filter system in an established tank you need to be more careful. BREX

Asked by: DAGMARK
3.5" will be on the outside of the tank, so allow about 5" in order to have enough room to insert or remove the filter. BREX
