Quantum Easy Z Alkalinity
Quantum Easy Z Alkalinity is the alkalinity half of the Easy Reefer 2-part system. It replenishes the carbonates your corals consume as they grow, holding your reef in a stable, healthy alkalinity range while topping up the supporting elements a thriving system needs. Run it alongside Easy E Calcium and browse the rest of our reef additives.
Why Alkalinity Matters
Alkalinity, also called carbonate hardness, is one half of the equation that builds coral skeletons. As your corals grow they pull carbonates straight out of the water, and if you do not replace them your alkalinity drifts and growth stalls. Easy Z restores those carbonates daily and carries supporting potassium, iodine, bromine, fluorine, and boron so your whole system stays in balance.
Features
How to Dose
Add Easy Z to a high-flow area of your sump. Dose daily based on your stocking level, and adjust to keep your alkalinity in range using a reliable test kit. As a guide, 1 mL per 100 L (26 gal) raises alkalinity by roughly 0.09 dKH.
| Stocking Level | Daily Dose |
|---|---|
| Lightly stocked | 0.50 mL / 100 L (26 gal) |
| Moderately stocked | 0.75 mL / 100 L (26 gal) |
| Heavily stocked | 1.00 mL / 100 L (26 gal) |

The Easy Reefer 2-Part System
Easy Z is one half of a balanced two-part dosing routine:

Dose both daily in equal measure for steady, balanced coral growth. Add targeted color with Bio-Gen, Bio-Metals, and Bio-Kalium.

FAQ
Do I have to use Easy E Calcium with it?
For balanced growth, yes. Alkalinity and calcium are consumed together, so dosing Easy Z alongside Easy E keeps both parameters stable. You can run Easy Z on its own to correct low alkalinity, but a full 2-part routine gives the best long-term results.
How much will it raise my alkalinity?
About 0.09 dKH per 1 mL in 100 L (26 gal). Always confirm with a test kit and adjust your daily dose to hold your target range.
Where should I add it?
Dose into a high-flow area of your sump so it mixes quickly. Avoid dosing Easy Z and Easy E into the exact same spot at the same moment.
How often should I test?
Test alkalinity a few times a week while you dial in your dose, then weekly once your levels are stable.
