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

Reef Essential® · Nutrient Control

The same science, dialed down for maintenance.

LR Nitrate Remover™ uses the same denitrifying-bacteria approach as HR Nitrate Remover, just dosed lighter — built for tanks already at or below 15 ppm that need steady, ongoing upkeep rather than a big correction.

Why a lighter dose matters once nitrate is under control

Once nitrate is already at or below 15 ppm, dosing at HR strength risks pushing it too low — and corals still need some nitrate for normal biochemical processes. LR Nitrate Remover feeds the same denitrifying bacteria — Thiobacillus denitrificans, Micrococcus denitrificans, and related species — at a gentler, steady rate instead.

Those bacteria colonize anoxic pockets in porous live rock and filter media, not just a sand bed, so a dedicated deep sand bed isn't required — this works well in bare-bottom systems too.

The ceiling this product is designed for — above that, HR Nitrate Remover is the better starting point.

Same end product as HR — nitrate reduced to chemically inert nitrogen gas, nothing left behind.

Bacteria colonize live rock and filter media just as well as a sand bed — no dedicated deep sand bed required.

What you're actually working with

The requirements and contents behind the dosing numbers.

01

Contents

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

02

Required parameters

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

03

Protein skimmer required

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

04

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.

05

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.

06

Switch to HR above 15 ppm

If nitrate climbs back above 15 ppm, move to HR Nitrate Remover for a stronger correction.

Dosing guide

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

Nitrate level Dose
0.1 – 1.0 ppm 0.1 – 0.5 mL/day per 100L (26 gal)
1.0 – 5.0 ppm 0.5 – 1.0 mL/day per 100L (26 gal)
5.0 – 10 ppm 1.0 – 2.0 mL/day per 100L (26 gal)
10 – 15 ppm 2.0 – 3.0 mL/day per 100L (26 gal)

Questions about this product

How do I know when to switch to HR Nitrate Remover?+
If your nitrate reading climbs above 15 ppm, switch to HR Nitrate Remover — it's the same denitrifying approach, dosed stronger to bring high nitrate back down before returning to LR for maintenance.
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.
