Red Sea NO3:PO4-X Nitrate & Phosphate reducer

Red Sea NO3:PO4-X Nitrate & Phosphate reducer, 1,000 ml.

NO3:PO4-X Contains a unique complex of carbons that are used by nutrient-reducing bacteria. Each carbon is utilized by different strains of microorganisms while maintaining the specific Carbon: Nitrogen: Phosphorus ratio required for each stage. The complex includes other organic bonded elements that are important stimulators in each stage of the reduction process. These metal and non-metals elements ensure steady bacterial propagation and complete nitrate reduction to nitrogen gas and the absorption and utilization of phosphate by the bacteria.

The fine control of the nitrate and phosphate levels provided by monitored dosing of NO3:PO4-X guarantees the gradual changes and accurate maintenance of the nutrient levels, preventing destruction of the zooxanthellae population that can cause UV shock and starvation of the corals.

Unlike some other low-nutrient regimes, correct use of NO3:PO4-X will maintain all of the beneficial micro fauna.

NO3:PO4-X is also recommended as a complete carbon source for use with carbon based de-nitrators.

NO3:PO4-X, available in 500ml and 1000ml bottles, also includes a measuring cup for easy dosing.

    Product Rating:

    I was sceptical about using this but I did anyway and I'm so impressed !! My nitrates were at 30 and above for several months in my reef aquarium and couldn't get them down no matter what I tried.. only after 3days my nitrates are now at 5 and dropping fast !! I wish I would've tried this earlier as I am now a loyal user of Red Sea NO3:PO4-X Nitrate & Phosphate reducer... Hope this review helps someone else. (Posted on 10/25/2016)
