PONDFORSE Canister Filter with Media

The PONDFORSE Canister Filter is an external filter that sits under the tank, with hoses running up to the water. Water passes through several layers of media inside the canister before returning to the tank. It comes with media, so you can set it up right away.

Three sizes

• Small: 172 GPH, about 7.9 x 6.1 x 12.2 inches.
• Medium: 225 GPH, about 10 x 8 x 14.2 inches, with a one-year warranty listed.
• Large: 264 GPH (1000 L), about 10 x 8 x 16.7 inches.

Flow ratings on any canister fall once media and hoses add resistance. Choosing the size above your tank’s bare minimum gives some headroom.

Adjustable flow

A flow control valve lets you turn output down for calm-water fish or planted tanks, and up for busier tanks. Turn it back up a little as the media fills with debris over time.

Why a canister

A canister holds more media than most hang-on filters and stays out of sight. It’s also quieter, since the motor sits in a closed stand. That makes it popular for planted tanks and bigger community setups.

Setup tips

• Fill the canister with water before powering it on, following the priming steps in the manual.
• Check every hose clamp and the lid seal for drips after the first hour.
• Put coarse foam first, then bio media, then fine floss.

Upgrading the media

You can swap in better media as you go. Coarse foam like the ALEGI sponge pad and a polishing layer like Aquatic Experts filter floss both cut to fit.

Who should look elsewhere

Keepers who want a big name and a long warranty may prefer a Fluval 307.
