Quick Overview

CaribSea LSM Sulfur media is the go to sulfur media for nitrate reactors.Its small particle size gives greater surface area per piece, allowing less overall volume of sulfur needed in the reactor.

Sulfur is a food source for bacteria that eliminate nitrates by converting them to nitrogen gas. The media will have to be replenished from time to time as it is slowly consumed by the bacteria.

1 Gallon

Caution: Use in sulfur nitrate reactors having a low water flow rate. The water leaving the nitrate reactor has a low pH and should be dripped over calcium reactor media to raise the pH before entering the aquarium.


Full Details

Nitrates in the marine aquarium can be controlled by the use of a sulfur reactor and elemental sulfur. A sulfur reactor will usually incorporate an up-flow type of reactor, as water will enter the reactor from the bottom and flow up to the top. The flow rate for a sulfur reactor should be very slow, as the bacteria will consume oxygen. The bacteria will also start to consume nitrogen when oxygen is no longer available. The chemical reaction that takes place releases excess hydrogen ions, which will also make the water more acidic. Nitrogen gas will also be produced during the process.

Carbon dioxide may also be produced during the chemical reaction that takes place, which would make the aquarium water a bit more acidic as well, making it imperative to run any effluent water through crushed coral, or calcium reactor media as that will raise the pH by dissolving the crushed coral.

  • LSM works great By Idol on 11/14/2016

    LSM sulfur media is fairly clean and cycles quickly. I have it running trough crushed coral and found that to work keeping the PH up. Note: If you use this with the Skimz NM152 you have to cut some coarse foam to put on the circulating pump return and the top feed going from the top of the reactor to the crushed coral reaction chamber as that will clog also with LSM media. Add a foam cut doughnut shaped rind to fit in the top lid and around the clear trap to prevent the Sulphur from getting in and stopping the flow.

Could I use this item in a Phosban Reactor to reduce nitrates?

Great question.
this media will only function in a nitrate reactor designed for the correct flow and air escape. Feel free to let us know if you have any further questions.
