Step 2 — Algae & Nutrient Control / HR Nitrate Remover™

Reef Essential® · Nutrient Control

Feeds the bacteria that turn nitrate into nothing.

HR Nitrate Remover™ doesn't strip nitrate out chemically — it feeds bioavailable carbon to denitrifying bacteria already living in your rock and sand bed, so they convert nitrate into inert nitrogen gas. Built for readings above 15 ppm.

For nitrate above 15 ppm Feeds denitrifying bacteria Needs a protein skimmer

The science behind the dose

How denitrification actually works

The bioavailable carbon this product provides feeds denitrifying bacteria — Thiobacillus denitrificans, Micrococcus denitrificans, and species of Serratia, Pseudomonas, and Achromobacter — wherever they've colonized anoxic pockets in your system: inside porous live rock, deep in filter media, or in a sand bed if you run one.

Those bacteria oxidize the carbon into carbon dioxide, and in the process reduce nitrate into chemically inert nitrogen gas. A dedicated deep sand bed isn't required — live rock alone provides plenty of anaerobic surface area, and plenty of bare-bottom tanks see great results with this product.

N₂
gas

The end product — chemically inert nitrogen gas, not a compound left behind in your water.

15
ppm

The threshold where you switch from HR to LR Nitrate Remover for fine maintenance instead.

Rock +
media

Denitrifying bacteria colonize anoxic pockets in porous live rock and filter media, not just a sand bed — no dedicated deep sand bed required.

What you're actually working with

The requirements and contents behind the dosing numbers.

Deionized water and bioavailable carbon sources — nothing else. The bacteria in your tank do the rest.

Required parameters

Minimum 15 ppm nitrate, dKH 7 or higher, pH 8.2 or higher before you start dosing.

Protein skimmer required

Must be used in a saltwater aquarium with a protein skimmer, added to a high water flow area.

Works with what you have

Feeds bacteria already present in your live rock, media, and sand bed if you run one — no dedicated deep sand bed required.

Simple directions

Shaking isn't required, though inverting the bottle 3–4 times helps if it's been sitting a while. Careful not to overdose.

Switch to LR at 15 ppm

Once your nitrate drops to 15 ppm or below, move to LR Nitrate Remover for lighter, ongoing maintenance.

Dosing guide

Based on your current nitrate reading. Must be used with a protein skimmer, added to a high water flow.

Nitrate level	Dose
15 – 30 ppm	1.5 – 3.0 mL/day per 100L (26 gal)
30 – 45 ppm	3.0 – 4.5 mL/day per 100L (26 gal)
45 – 60 ppm	4.56 – 6.0 mL/day per 100L (26 gal)
60 ppm+	6.0 mL/day per 100L (26 gal)

Nitrate already under 15 ppm?

Or dealing with a different nutrient entirely — here's the rest of the line.

LR NITRATE

LR Nitrate Remover™

Same approach, dosed lighter for readings at or below 15 ppm.

CARBON

Bio-Active Carbon™

For odor, tannins, heavy metals, and toxins.

PHOSPHATE

Phosphate Remover

Pulls out both free and chemically-bound phosphate.

CORALLINE

Sweet Coralline™

Feeds coralline algae growth directly.

Questions about this product

How do I know when to switch to LR Nitrate Remover?+

Once your nitrate reading drops to 15 ppm or below, switch over to LR Nitrate Remover — it's the same denitrifying approach, just dosed for lighter, ongoing maintenance instead of bringing high nitrate down.

Do I need a protein skimmer to use this?+

Yes — this product must be used in a saltwater aquarium with a protein skimmer, added to a high water flow area.

Do I need a sand bed to use this?+

No. Denitrifying bacteria colonize anoxic pockets in porous live rock and filter media just as well as in a sand bed. A dedicated deep sand bed can help, but plenty of bare-bottom tanks see great results with this product without one.

What's actually in this product?+

Deionized water and bioavailable carbon sources. Shaking isn't required, though inverting the bottle 3–4 times helps if it's been sitting for a while.
