JBL Symec Vl

JBL Symec VL is a filter fleece mat that removes cloudiness and fine particles from freshwater and marine aquarium water. The 3 cm thick fleece is cut to the shape of your filter compartment, so one mat can be adapted to many filter types. It goes in as the final stage, where it polishes water that has already passed through the coarser media. Made from water-neutral synthetic fibre, it releases no pollutants into the aquarium, making it a simple way to keep the water looking clear.

Key features of the JBL Symec Vl

• 3 cm thick fleece mat
• Cut to fit your filter
• Removes fine particles and cloudiness
• Water-neutral synthetic fibre
• For freshwater and marine tanks

Fitting and changing the fleece

Cut the mat slightly larger than the filter compartment so it sits snugly against the walls, as water always takes the easiest route and will bypass a loose edge. Because it is the final polishing stage, place it after the sponges and biological media, where it catches only the finest particles. In canister filters it can sit at the top of the last basket, and in sumps it can be laid over a filter tray. Swap it when it turns brownish or when flow drops; in busy or heavily fed tanks this may be every week or two. Keeping a spare cut piece ready makes changes quick.

Good to know

The fleece can be rinsed, but JBL recommends replacing it with a fresh piece rather than reusing it.
