Sulfur reactors are able to remove nitrate in both salt and freshwater tanks. Size: 130x130x480mm, HP MR 15040 The recirculation method is far more efficient than simple single pass filters. Aquarists usually go through a lot of trouble trying to reduce nitrates. Since sulfate is another bi-product of the chemical reaction within the reactor, crushed coral also absorbs this and removes it before water re-enters the aquarium. In most cases, this takes about a month, until the reactor is loaded with enough bacteria to complete the chemical reaction. I continue to run a sulfur based nitrate reactor on one of my reef tanks, and it’s maintained its chemical reaction with little to no maintenance for years, keeping nitrates at undetectable levels. This extremely effective process was translated for use in numerous public aquariums with great results. Neither bio-pellets nor traditional nitrate reactors are maintenance free and without consequence. According to Equation (1), when nitrate is reduced to nitrogen gas, sulfur is oxidized to sulfate and an H+ proton is released. The IPTEI is intended to hang on the walls of … Let the gas out every couple days. As the water slowly rises, oxygen is removed, making the water anaerobic farther up in the contact chamber. Residual nitrate often accumulates within our tanks. Nitrate levels in the tank hovered between 16 ppm to 25 ppm, and even after large water changes nitrates quickly shot back up. The crushed coral media will dissolve over time and need replaced, but even that can last for extended periods. ATO – Auto Top off – for automatic replenishing evaporated water in reef aquarium.
