Nitrate and Phosphate Remover
An ideal substrate for colonization by beneficial denitrifying bacteria

Releases organic carbon molecules for the metabolization of nitrate

Facilitates the removal of soluble phosphates

Enhances water clarity


100% bio-based

Reduces water changes and maintenance
Removal of nitrate and phosphate from aquarium water by certain bacteria requires a suitable organic fuel' for bacterial metabolism. AquaLife DeNITREX supplies that organic substrate releasing it into the aquarium environment at precisely the rate it is consumed by the bacteria. Numerous aquarists have learned that this method is superior to dosing schemes using vodka or another organic substrate added periodically by the aquarist. Furthermore, the use of solid DeNITREX biopellets significantly reduces maintenance chores, compared to hand dosing. DeNITREX also facilitates the removal of soluble phosphates, and can be used as the sole means of phosphate removal in a properly nutrient-managed system.

Nitrate (and phosphate) removal occurs via more than one physiological pathway, but in all cases the nitrate-rich bacteria themselves are either consumed by filter-feeding aquarium inhabitants or are removed via the protein skimmer. Maintaining adequate protein skimming is essential to any reef aquarium maintenance program.
Dosage and Instructions: AquaLife DeNITREX should be used in a fluidized bed reactor, canister filter or similar device through which moderate water flow can be maintained. This results in an optimal denitrification rate. We recommend a pre-filter to remove particulate matter before it enters the reactor or filter chamber.

Use 1 cup (237ml) DeNITREX for every 50 net gallons of aquarium water. After installing the reaction vessel and initiating water flow through the biopellets, monitor dissolved oxygen and pH of the aquarium for the next 48 hours, as some systems may experience a slight decrease in both. Maintain protein skimming and normal water flow through the system to keep dissolved oxygen at saturation. Use an alkalinity booster, such as AquaLife Simple Science Alkalinity to increase pH, if needed.
If the aquarium already has a low nutrient profile, with nitrate below 5 ppm and phosphate below 0.02 ppm, use of DeNITREX should maintain or reduce these levels.

If the aquarium is already overloaded with nutrients, that is, if the initial nitrate level is greater than 5 ppm or if phosphate is greater than 0.02 ppm, then use 10 grams of DeNITREX per ten net gallons.

For optimal results, add AquaLife Activate according to label directions, to seed the biopellets with beneficial denitrifying bacteria. This greatly reduces the time needed to establish system equilibrium.

Allow at least one month to observe reduction in aquarium nutrient levels. As much as two months may be required in the case of high nutrient concentrations. Supplemental additions of AquaLife Activate will facilitate the denitrification process during this time.
Maintenance: After several months, the volume of DeNITREX biopellets will be visibly reduced, due to consumption of the biopellets during the process of denitrification. The rate at which the biopellets reduce in volume depends upon the aquarium nutrient level, with higher levels resulting in faster degradation. Simply replenish the biopellets to their original volume and continue to operate the system normally.
For aquarium use only. Keep out of reach of children.
