Will this bio wheel fit a marine land penguin 275

Can you adjust the flow rate?
Answer by ChewyApr 23, 2018
There is a gray lever that opens and closes, allowing water movement at mid-level. If closed, the filter will only pull water from the bottom of the tank.

My bio wheel will not spin.
Answer by ChewyDec 31, 2019
Usually when the Bio-Wheel won't spin either the water level is low, the filter system needs cleaning or the Bio-Wheel bearings are misplaced or dirty. Take the filter off of the tank, take it apart, and give it a good cleaning using warm water and distilled white vinegar. Make sure to pay close attention to the impeller, motor, intake tube, impeller housing and bearings. Rinse them well after cleaning and re-install.

Does it come with filter cartridges?
Answer by ChewyDec 22, 2018
A filter cartridge is included with purchase.

King of filters

I've used them all but, in my opinion, these old-style Penguins and Emperors are the best filters made. They are work horses and built like a tank. No cheap, thin, flimsy plastic on these. I have two 20+ year old Emperors running on a tank now, and they've never given me any problems. The bio wheels spin and the impellor doesn't rattle. With a little maintenance these will last you a long time.

pretty good

The instructions on how to put it together were a little confusing but once I figured it out it works well, i will say though it is definitely bigger than I expected it to be so just be mindful of that, I had to buy the 50gallon one. I was barley able to fit it next to my other filter on a 50 gallon tank. I haven’t had it for to long but so far everything looks great.

Bio wheel filter

The filter system was a good price and came quickly. Previously I had a bio wheel filter that lasted 20 years. This new is working great.

Do Not Buy This

Full disclosure, I purchased this last year for a tank I just assembled in the last two months. Yesterday, it stopped working. Not even two full months, and it just stopped working. Sadly, I am not made of money. I can’t return it, but now I have to wait to replace it. (There are no fish in the tank yet, thankfully.). I’m just so disappointed, because I was finally about to populate the tank. And essentially, my money has gone down the drain. That just makes me sad.

Don't buy its cheap

I thought I would give this project a try, but with in a 2 months the cheap plastic propeller broke, making it junk. I should have gotten another Aquaclear, I've bought 4 of them and I would recommend it to anyone who is looking for a great filter plus out of all the canister filters I've have, the Aquaclear is the easiest to clean up and you never have to worry about it leaking.

Excellent filter

My aquarium's previous filter stopped working and I needed to keep my aquarium clean. This one is smaller but works great. Will be ordering another one soon.

The filter did not clean the tank at all and was extremely loud for the type of filter. Lots of "buzzing or humming. Tried to contact chewy about returning it and never received the email back.

Almost perfection

I received our new Marineland filter in a timely manner. When I installed it, I found that the bio wheel wouldn't spin. Luckily we had 2 older ones, so I replaced the defective one and bazinga, it works! We love Chewy, their Pawsome associates & their prices!

I bought this pump in March. It has stopped working and the wheel won't spin. I contacted the company but never heard back from them.
