Grow Macro Algae to Control Nitrates and Phosphates!

Cultivating chaetomorpha algae in the Tunze MAR-3181 makes controlling your aquariums nutrients clean and easy. Tunze's algae reactor can be placed internally in your sump, or placed externally if you do not have room in your sump, or just don't have a sump. The reactor uses an external lighting solution provided by the Tunze Eco Chic Refugium Light that can be fully submerged underwater for maximum efficiency. To help increase the efficiency of the external light, water that is input into the reactor creates a spinning effect that forces the algae to circulate inside the MAR-3181. One of the biggest downsides to an algae reactor is the maintenance, and Tunze has made harvesting super simple with an easy to remove lid that is held on by large thumbscrews and only takes about a minute to remove the algae, harvest it, and replace the cap.
