Maintenance, not 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.

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.
