Aquarium Refugium With Rio Powerhead

Want a place to acclimate new arrivals to your aquarium, provide a haven for injured fish or invertebrates, or just have a special area to raise things like plants and food for your aquarium's inhabitants? Then an in-tank refugium is the best option for you.

In-Tank Aquarium Fuge With Powerhead

No need for a separate external refugium



Mount this refugium right inside your established or new tank with the included suction cups and create a home for macroalgae and some live sand and live rock for maximum benefit. Also included is a Rio powerhead to keep water circulating through the refugium, for the best gas exchange and benefit.

Reef Aquarium Refugium Uses

What a refugium is used for

Reef aquarium refugium



Besides being a "jail" or "timeout" area for naughty fish and invertebrates, refugiums are often used to raise macroalgae and other creatures that contribute to the health and stability of reef aquariums. For instance, macroalgae improve oxygen levels in the aquarium and help filter the water.

Refugium Plants and Algae

Plants and algae for refugiums

Do you have an in-tank refugium?

Do you prefer in-tank or hang-on?

    This lens is so, so out of my area of knowledge but as usual you have done a beautiful job. :)
  • sharpturn May 13, 2009 @ 5:05 pm | delete
    Im thinking of getting one of these for myself.

    Good info.

    You've got a point there. I removed the part about using an in-tank fuge as a QT area. Thanks for your input!
  • arcprolife May 22, 2008 @ 10:39 am | delete
    I have 2 in tank refugiums that work great. I disagree with using them as quarantine. The purpose of a QT tank is to keep parasites out of the main tank. Using the in-tank refugium allows the parasites right into the main tank. Great for macroalgae NOT quarantine
