Step 3 — Aragonite Enhancers / Aragonite B™
Reef Essential® · Aragonite Enhancer
The "A" in CAM — carbonate, hydrogen carbonate & buffers.
Aragonite B™ provides carbonate, hydrogen carbonate, and buffers that stabilize pH and build strong aragonite. Use alongside Aragonite A and C for the full major, minor, and trace element profile.
Too low burns tissue, too high scorches tips
Alkalinity is one of the most critical parameters to monitor. Let it dip too far and corals begin losing tissue; let it climb too high and coral tips burn. Carbonates and hydrogen carbonate give your water its buffering capacity — the ability to resist pH swings — which is what Aragonite B is built to maintain.
When aragonite elements run low, corals can form brittle calcite instead of dense aragonite — leading to lower bone density and slower growth overall.
What's in the bottle
Contents
Deionized water plus carbonate, hydrogen carbonate, and buffers.
Use as a team
Must be used alongside Aragonite A and C to provide the full major, minor, and trace aragonite element profile.
Directions
Shaking isn't required, though inverting 3–4 times helps if it's been sitting a while. Add to high water flow; safe on a dosing pump.
Powder option
Also available as bulk powder, formulated alongside Aragonite A powder for a 1:1 dosing ratio — mix 110g per liter, then dose ½ capful (5mL) of the resulting solution.
Reef aquariums only
Formulated for reef tanks, not general saltwater setups without coral.

Dosing guide
1 mL/100L (26 gal) raises alkalinity by roughly 0.1 dKH (1.8 ppm).
| Stocking level | Dose |
|---|---|
| Lightly stocked | 0.50 mL/day per 100L (26 gal) |
| Moderately stocked | 0.75 mL/day per 100L (26 gal) |
| Heavily stocked | 1.00 mL/day per 100L (26 gal) |
| Or as required | to maintain 7.4–10.5 dKH alkalinity |
