Refugium General Info
A refugium is a tank that shares water with the main aquarium--much like a sump. Some refugiums hang off the back of the tank and some sit under the tank. The refugium can be used to grow macro algae and to provide a safe haven for animals that may be preyed on in the main tank.
We carry a number of CPR Refugiums, including hang-on and sump style.
- Refugiums provides a controlled growing area for macroalgae, reducing the unappealing algae in the main tank. A great benefit of this is that the algae in the refugium will consume phosphates, nitrates and ammonium.
- Organisms you might create a safe haven for in a refugium include "feeder" organisms such as feeder fish, copepods and amphipods. These organisms can be reproduced safely and then added to the main tank as needed.
- New fish or fish that are being bullied can find safe haven in a refugium.
- A refugium increases the amount of water in your system, which is always beneficial.
Refugium lights are small compact lights with full spectrum bulbs. Although many lights could be used for a refugium, these lights are either designed specifically for refugiums or were designed with refugiums in mind.
