Questions & Answers

47 Customer Questions

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.

When we were setting up our new 20 gallon top fin fish tank we have a question about the water filter . The water filter is plugged in but do we leave the water flow adjusted on open or in closed
Answer by ChewyDec 03, 2019
The filter can be used either way, depending on the needs of your tank. If closed, this filter will pull from the bottom of the tank only. If opened, the tank will filter water throughout the different depths of the tank.

Works great..until it stops working

I had originally ordered this filter about a year and a half ago.It worked great until one day I woke up and it was not running anymore.I cleaned it up replaced the filter and still nothing. Chewy was kind enough to send me a replacement even if I had purchased the item 6 months ago.The replacement was working fine right up until 2 weeks ago.It started to make a horrible grinding noise I managed to finagle the intake tube which helped the noise a bit but it still was very loud.Today I officially retired the annoying hunk of garbage.Do yourself a favor and order a different type of filter

Marine, land filters, rock

I have been using Marine land, penguin filters for more than 10 years I have never once had a problem with them, except you have to clean them occasionally

Nope not worth it

These work great for about 10-20 days and then they drastically slow down until eventually they just stop working. Even after changing the filter, cleaning every part of the pump it's still barely working. Buy something else.

Rattle buzzing noise will drive you crazy

Tried everything to stop the rattling noise but no luck. Seems much cheaper construction than much older model I already have. Noise will drive you nuts.

Didn't last a month.

I followed all the instructions and cleaned it multiple times but it stopped working 3 weeks after I bought it. I bought the 50gal filter for my 40gal aquarium. I do not recommend buying this.

Learn your product Great product will last yrs

This is a great product have been using for 2yrs not a problem other than my own ignorance.many folks here having problems ive experienced not knowing how to work a good filtration system. If the filters are clogged or water level low the bio wont spin you still have to clean your tank after water change make sure suction pipe is not jammed in or pushed out easy does it..fill the pump with water it gets it going. This product doesn't just quit working. And its only loud when the tank isnt filled to proper level.

Top notch very happy

I have a 55 gallon aquarium. With two yellow bellied sliders. This filter keeps the water clean. Is quite and has a nice water fall effect. Peaceful. I have to clean the filters once a week since turtles are very messy.
