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.

The maximum head pressure height is 31.5" for the Comline 2500 pump that comes with the Tunze MAR-3181 (https://www.bulkreefsupply.com/mar-3181-macro-algae-reactor-tunze.html).

Can you connect this to the apex EL?
If so what's needed ?
Question by: Jerry Ebner Jr on Feb 7, 2020, 7:39 AM
Hey there,

The pump for the 3181 cannot be controlled by Apex but if you plug the light into the energy bar you can use that as a timer to turn it on and off.

How much chaeto (from algae barn as sold by you guys) would you recommend to start with?
2 oz, 4 oz, more?
Question by: TL on Feb 6, 2020, 12:36 PM
Hey there,

I would start with a 4oz ball, it will grow pretty quickly to start out.

Take care

Could u run this off a manifold with a gate valve to adjust flow ?
Question by: Christian Marino on Nov 8, 2019, 8:54 PM
Hey there-

Thank you for reaching out to us! This can indeed be ran off a manifold, however the algae scrubber also comes with a DC controllable tunze pump as well.

Take care!

can you converted to a hang on algae reactor?
Question by: Beverly on Jul 26, 2019, 6:25 PM
Hey there-

Great question!
While these can be used externally it does not have a bracket for hanging on the back of aquariums. Due to the weight this reactor will have once filled I would recommend just sitting it on the ground next to the tank or under the stand similar to a canister reactor.
Happy reefing! :)
