Undergravel Filters are manufactured with a unique design that allows uniform flow across
the entire tank. Heavy duty injection-molded plastic holds up under the heaviest rocks
and tank d�cor. UGF filters are easy-to-install and include fish protectors on the flow
spouts and raised tube connectors to keep gravel from falling beneath the plates. Ideal
for use with air pumps, power heads, and refillable carbon cartridges. 30" x 12" model
