Quantum Reef Essential LR Nitrate Remover 5L is a liquid carbon-source supplement for reducing nitrate in marine and reef aquariums with readings of 15ppm or below. The 5L bulk pack suits aquarists who have established their ongoing dosing requirements.

Choose the correct nitrate range

LR means Low Range. Test nitrate before selecting and dosing this product. Quantum recommends HR Nitrate Remover when nitrate is above 15ppm, then switching to LR once the reading reaches 15ppm or below.

How it works

LR Nitrate Remover supplies bioavailable carbon sources to denitrifying bacteria in filter media, deep sand beds and the inner pores of live rock. These bacteria use the carbon sources while reducing nitrate to nitrogen gas. Quantum describes the formulation as designed to reduce nitrate without promoting nuisance bacterial slime.

Requirements and restrictions

• For saltwater aquariums with a protein skimmer.
• Nitrate: maximum 15ppm.
• Alkalinity: 7 dKH or above.
• pH: 8.2 or above.
• Do not use in aquariums containing live plants.
• Add directly into an area of high water flow. Do not overdose.

Daily dosing for the 5L pack

Quantum's doses below are per 100L of actual aquarium-system water volume per day. Include water in the aquarium and external filter, subtracting volume displaced by rock, media, ornaments and other contents.

• Nitrate 0.1–1.0ppm: 0.1–0.5mL daily per 100L.
• Nitrate 1.0–5.0ppm: 0.5–1.0mL daily per 100L.
• Nitrate 5.0–10ppm: 1.0–2.0mL daily per 100L.
• Nitrate 10–15ppm: 2.0–3.0mL daily per 100L.

Scale the dose to your actual water volume and nitrate reading, and follow the current bottle label. Quantum lists the 5L cap as approximately 20mL; use a suitably accurate measuring device for small doses rather than estimating a fraction of a cap.

Use and pack size

Shaking is not required. If the bottle has been standing for an extended period, the existing product directions advise inverting it three or four times before use. Quantum confirms the product can be used with a dosing pump.

This pack contains 5,000mL. How long it lasts depends on system water volume, nitrate readings and the daily dose required; it is not a fixed-capacity, one-off treatment.
