Nitrates in my 187 gallon reef tank had been hovering around 1 ppm so I used the product to boost levels to 5 ppm, resulting in better colors for my SPS. Of the inorganic species, nitrate is often, but not always the highest in concentration. Typically, about 20-25 percent of the water in the tank is siphoned out and replaced with new water.

To help offset the drop in pH, a layer of calcium media is placed above the sulfur media which will help increase pH and also enrich the water with calcium before it exits the reactor. The principle of NNR or Natural Nitrate Reduction filtration is that the nitrifying bacteria do all the work. Nitrate is the end result of the breakdown of organics. But if one keeps reef fishes, believe me it’s there. If the results look okay, check the salinity and adjust as necessary. You should also be mindful that nitrates can be present in tap water.

Let me stress that it is important to take things slow and raise nitrates gradually over a few weeks. The primary way to lower nitrite levels in the tank prior to cycling, or when experiencing an increase after cycling, is to perform a series of water changes. Test the basics: ammonia, nitrite, nitrate, alkalinity and pH. The key to any macro algae farming is regular harvesting. It is typically formed in aquaria through the digestion of foods, and in many aquaria it builds up and can be difficult to keep at natural levels. Water changes can be critical for a thriving reef, but their impact on nitrate and phosphate can be limited. How To Reduce Nitrate. Similarly, if you do small 10% water changes, don’t expect your nitrates to change a whole lot. In reef tanks, nitrates are necessary in small quantities to fuel the photosynthesis.
