With an influent concentration of 30 mg $700.00. Final recommended flow through your reactor should be 3-4 liters per hour per liter of sulfur media as long as the effluent reads zero nitrates. Nitrates elimination by autotrophicdenitratation on sulfur by Christophe Soler. Break in time and efficiency is greatly improved with controller. Introduction. The amount fed is based on the existing nitrate level, and it can be tricky to dose the right amount, at the right time. Kostenlose Lieferung für viele Artikel! Add to Cart + Wishlist; SAVE 10%. No questions asked yet. When pH is above 7, the reaction shifts to the left side and the ammonia is predominant. Residual nitrate often accumulates within our tanks. Whatever the culprit, nitrate is difficult to totally eradicate from the marine aquarium. Often aquarists who implement traditional nitrate reactors are either constantly dosing, or adding a secondary reactor to buffer ph and remove excess co2. If you’re considering a sulfur based nitrate reactor, you’ll notice they carry a higher initial cost than bio-pellet reactors or a few other nitrate removal methods. Nitrate levels in the tank hovered between 16 ppm to 25 ppm, and even after large water changes nitrates quickly shot back up. Thread starter greg 45; Start date Jan 25, 2016; G. greg 45 Active member. The NR624 nitrate reducing sulfur reactor will hold roughly 16 pounds of media and is well suited for reef aquariums up to 600 gallons. To help offset the drop in pH, a layer of calcium media is placed above the sulfur media. Enter sulfur based nitrate reactors. The start-up period, temperature effects, and effects of different feed solutions were evaluated. Hi, I clean a guy's 500 gallon reef and his only issue is high nitrates. SAVE 10%. Sulfur nitrate reactors use small beads of elemental sulfur in a contact chamber. Aquarists usually go through a lot of trouble trying to reduce nitrates. These radicals exist at pH values near 7 mainly as S•-. Jeremy Gosnell has been an aquarist for nearly all of his life. Nitrate is also a major cause of nuisance algae problem. $349.95.
