Red Sea NO3:PO4-X Nitrate & Phosphate reducer

Red Sea NO3:PO4-X Nitrate & Phosphate reducer, 500 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.

    i don't know what i would do without nopox, seriously. i have 42 fish in a 120 gallon mixed reef tank and i feed like my fish are dying. i have measured my nitrate uptake every day without nopox and i have a 5ppm increase per day. that means a water change would be needed every other day. instead i add 15ml of nopox per day and my nitrate is .5. half of 1ppm. i love this stuff!!!! as long as you have a protein skimmer this works wonders!!
