Refugiums are a great option for growing algae to help control nutrients, as well as ideal conditions for harboring micro fauna. With three different sizes the AquaFuge2 is a simple to use hang on back refugium. With a recently redesigned black acrylic backing and unique baffle system, keeps the algae and substrate in the refugium and not the display tank.

Refugiums are also a great way to introduce new fish or corals to a tank while giving them a place to feed and acclimate to a new system without competition or added stress from other fish in the system.

The Small AquaFuge2 Hang on Back Refugium with LED Lighting - CPR Aquatics (https://www.bulkreefsupply.com/small-aquafuge2-external-hang-on-back-refugium-with-led-ligthing-system-cpr-aquatics.html) dimensions are 13.5" L X 4.5" W X 12" T so if you only have 10" across the back of your tank, this will not fit.

Is there a way to put a filter sock on this? If so which do you recommend?
Question by: Joe Cerillo on Dec 13, 2021, 5:47 PM
Thank you for reaching out with your question. There isn't really a good way to add a filter sock to the AquaFuge. you could add some filter floss or pad in the return section if you wanted to add some mechanical filtration.

Hey there,
Will this refugeium work for a jbj rl 45 to maintain a stable pod population?
Question by: Alex Cheshmedjiev on Jun 6, 2017, 5:04 PM
That depends a little on what you mean by a stable pod population, but as long as you have a suitable environment for pods to grow and reproduce, without any predators present, they will be able to live and maintain a population in the back refugium area. Depending on your goals for this (whether to provide a constant source of food for a micropredator such as a dragonet or simply as a small source of occasional pod food to the tank), this population may or may not be sufficient.

Happy reefing!

hey i was wondering if this will be big enough for a 34 gallon tank reef tank!!!!!
Question by: nick stokes on Apr 7, 2017, 1:04 PM
Hey there,
This hang on refugium should be a good fit for your tank. It will provide a good refuge location for a nice pod population as well as a good growing area for some macro-algae, although you may find the supplied LED light is not optimal for growing algae and if one of your main goals is nutrient removal through algae growth, a more powerful light with proper spectrum might be advantageous.

Have a great day!

I have exactly 4 - 7/10th inches from the back of my tank to the wall,,, will this fit? it's a rimmed tank, the measurements are from the end of the rim and the wall
Question by: John Lee on Nov 25, 2016, 1:01 AM
