Questions & Answers

20 Customer Questions


Do you have to have a pump for this?

Answer by ChewyMay 25, 2018
A pump would be needed for proper filtration and circulation.

Can it work in a pond woth ducks?

Answer by ChewyMay 18, 2018
The flat box filter would work for a duck pond if you can keep the bottom of it fairly clean. That can be hard to do with ducks as they typically bring a lot of mud into the pond.

Can filter media be put inside this filter? I'm intending on having a goldfish pond and their filters need lots of media.

Answer by ChewyJun 06, 2018
This flat box filter does not use filter media, it uses coarse and fine foam pads, which are included.

Will this work in a 40 gallon tank for fresh water fish?

Answer by ChewyApr 16, 2018
This product is intended for small to medium ponds. This filter works to keep your pond water clean, healthy and clear by filtering from 250 to 500 gallons.

No pump included

Although pictured in photo 2 & 3 no pump will arrive with this item. And who knows what else it needs as no set up instructions are included either sigh

Doesn't filter small stuff

Also doesn't pump by itself, hose is very short, and needs duplicate adapters.
