25kg EGFM (Eco Glass Filter Media) - Grade 2

As a guide:

Grade 1 is the equivalent of 16/30 filtration sand.
Grade 3 is the equivalent of pea gravel.

Eco Glass Filter Media (EGFM) is the environmentally friendly filter media and a viable alternative to silica sand; made from glass recycled in the UK, it doesn't involve intrusive mining and the use of scarce resources.

EGFM has the green credentials, and with its superior performance is also cost effective against sand.

Benefits of EGFM over Sand

• More Efficient
• Cleaner
• Less dense therefore less is needed to fill the filter
• Doesn't degrade

“The performance of recycled glass media was superior to sand, both for the amount of suspended solids removed and for the amount of influent treated; before a back wash cycle was required”
