Grow macroalgae without a refugium!

Growing algae like chaetomorpha will greatly help your reef aquarium with nutrient issues like nitrate and phosphate. The Skimz MBR157 Macroalgae reactor is designed to be placed in any sump and includes a LED lighting system designed for algae growth.

Dimensions - 8.25" L x 8.25" W x 22.5" H

  • DC Controllable Quiet Pro Pump 
  • Quartz Sleeve
  • LED Lighting System
  • Integrated algae containment plates


Refugiums are a proven nutrient reduction method that grow specific algae like chaetomorpha that intake nutrients such as nitrate and phosphate. However, refugiums take up a lot of space, usually make a mess of your sump, and they are not efficient at directing flow through the algae. The Skimz MBR157 Macroalgae Reactor allows you to grow algae within a contained system, letting you have full control of the flow rate through the reactor and direct contact with the LED lighting system.


LED Lighting

All Skimz Macroalgae Reactors include a high power LED lighting system that is encased in a crystal clear quartz sleeve. Quartz sleeves provide the highest optical clarity allowing much more light to pass through when compared to typical glass. The LEDs were selected to provide excellent nutrient intake while providing rapid growth. As water flows through the reactor and contacts the quartz sleeve, it will actively cool the LED lights. We do not recommend turning the light on without water flow through the reactor. 


Controllable Quiet Pro DC Pump

The included DC pump gives you full control of the flow through the algae. The highly efficient Quiet Pro DC pumps run extremely quiet, using a brushless 6-pole synchronous motor. They also utilize a slow start-up mode that gradually builds up speed over the duration of about 20 seconds. With 9 different speed settings, dialing in the reactor is as simple as pushing up or down on the pump controller. 


Max Tank Volume Recommendation - 180 Gallons

The size of macroalgae reactor your aquarium requires will vary depending on the amount of nutrient reduction needed. We suggest using the largest macroalgae reactor you can fit in your sump.

Product Questions

Would this house copepods, or would they get destroyed by the pump?
Question by: kevin dawson on May 11, 2017, 10:49 PM
Hey there,
While this is not the intended function of the reactor, it is almost inevitable that copepods will want to live in the macroalgae. Their survival odds would likely be very similar to that of making it through our return pump from a regular refugium.

Happy reefing!
Answer by: Zack on May 14, 2017, 5:19 PM
Is there any good reason to have this reactor if you have a large refugium.
Is there any added benefits vs refugium?
Question by: Dale Hart on Oct 30, 2017, 5:51 PM

This is essentially a compact refugium for those who do not have the room for one in their sump. Combining the two wouldn't really add any sort of benefit. :-)
