Here is a pure granular elemental sulfur (sulphur), with sulfur reducing bacteria right on it. This product can be used in a number of ways, and accomplishes the same job of nitrate reduction as our NO-NO3®. This product is ideal for dual chamber reactors, using our A.R.M.® in one reactor and placing the L.S.M.® in another. This results in a system that delivers elevated calcium, and reduced nitrates.

LSM™ is intended for use in experimental sulfur based nitrate reduction equipment or systems. Nitrate and pH test kits are required to fine tune any nitrate reducing equipment. Sulfur based nitrate reducing bacteria require an oxygen depleted environment. Be aware that this process may strongly acidify surrounding water. A typical system employs two separate canisters with a means to control water flow rate through the reactor. The first canister contains the LSM™. The second canister is filled with aragonite to neutralize acidified water and supply calcium ions as a by-product of neutralization. LSM™ can be placed in any oxygen restricted environment. As with any experimental project, we do not recommend putting a significant amount of sea life at immediate risk, nor risk the health of well established systems without a thorough testing of the effluent parameters first.

Note: Nitrate reduction with sulfur may produce an odor. Due to the experimental nature of sulfur based de-nitrification, the manufacturer accepts no responsibility for the use of this product.

Guidelines for LSMTM Use in Reactors and Modified Jaubert Systems:
The most common application for LSMTM would, of course, be in reaction chambers. Before going into the details here’s a review of the basic concept of autotrophic sulfur denitrification:

In the reactor, sulfur is a food source for bacteria that also eliminate nitrates by converting them to Nitrogen gas. In time the bacteria break down the elemental sulfur and also create sulphate and hydrogen. Both of these by-products can have a negative impact on pH, by bringing the pH down, so it is important to make sure that the effluent from any sulfur reactor is adjusted back to a pH that is acceptable for a marine system.
