Product Questions

1) You would have to seed the reactor with Chaetomorpha?
2) Describe the water inlet and outlet.
3) The top of the reactor would have to be out of the water?
4) The picture shows it lights up when in use. Is that the case or just a dramatization?
Question by: LJT on Apr 28, 2017 9:59:00 AM
Hey there,
Chaetomorpha and other macro-algae do require a cutting or tissue sample to get the algae culture started. From there, the algae should grow and fill in the reactor as nutrients are available. The reactor works through an up-flow design and the water is returned back to the bottom internally and will exit at the bottom. Because the light's wiring connections are at the top of the canister, you will need to ensure that these are above the water. The reactor utilizes internal LEDs to provide light to the algae and will produce a reddish light with the idea wavelengths to promote plant/algae growth.

Happy reefing!

What macroalgae is suggested with this reactor? Have you considered having a starter kit? Is it worth a brstv episode to review this and other products which substitute for a refugium?
Question by: Mike on Apr 28, 2017 5:15:00 PM
Hey there,
This reactor can be used with a variety of macro-algae types, but the most popular and easiest to find by far would be the Chaetomorpha types. I'm afraid we really don't get into selling any livestock and as a result wouldn't really be able to offer a complete starter package. There are lots of sources both locally and online that should be able to provide you with a small starter culture.

Happy reefing!

I am very pleased with this purchase. How often should I perform maintenance and what would that be? Will the algae need to be manicured at some point?
Question by: Mike on May 13, 2017 10:20:00 AM
Hey there,
Glad to hear you're liking your new reactor! We've been very pleased with the results we've seen so far as well. The maintenance interval will depend quite a bit on your nutrient levels in your tank, but a good starting point would probably be every 1-2 weeks. You will need to periodically harvest a portion of your algae mass so that you are completing the process of exporting the bound-up nutrients in the algae bio-mass, and also providing space for new growth.

Happy reefing!

Full Details

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 MBR127 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 20 different speed settings, dialing in the reactor is as simple as pushing up or down on the pump controller. 


Max Tank Volume Recommendation - 100 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.

    Easy to install. O-ring on the top seal can be tricky. In a little over 2 weeks there has been visible growth the chaeto. The sump on my RedSea max 260 makes this a sleak option and a clean looking setup. I plan on getting on for my new 180 tank.
  • Build Quality is amazing By Eric on 5/5/2017

    I own several Skimz products and I am always impressed by their build quality, this item is no exception!
