Aquariums with skimmer boxes can be used with many types of filter systems from wet/dry trickle filters to single or multistage canister filter systems. Skimmer boxes help to meter the flow of water entering your filter system and protect your aquarium from completely draining in the event of a power outage. The light hood, installation parts, and a roll of DLS material are provided. This aquarium is perfect with the Vanguard Wet/Dry Filtration Set-up. Comes with 1 light hood with one 36" light fixture. Bulb sold separately.
