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
Perfect, just like the product name implies. by Gordon11/29/2011
I've used under-gravel filters before and have always liked the results. This one fit my tank perfectly and had options as to were I could have the riser tubes coming up along the back of the tank. Thank you.
