​

Whether you're just starting out or want to streamline your reef maintenance, InOne gives your corals the essential elements they need — in one single, balanced solution.

​

Before introducing InOne to your aquarium system, we recommend ensuring your key parameters — calcium, alkalinity, and magnesium — are at your desired baseline levels. You can use individual Reef Zlements supplements to make these initial adjustments if needed.

​

Dosage Guidelines:

• Initial Dose: Start with 5 ml of InOne per 100 litres of aquarium volume daily.

• Adjustment Phase: Increase the daily dose by 2.5 ml per 100 litres weekly, until alkalinity and calcium levels stabilize.

​

Once your system stabilises, you can monitor either calcium or alkalinity on a regular basis to maintain consistency. We suggest using calcium as the primary control parameter, as most hobby-grade test kits offer more reliable sensitivity in detecting calcium level changes.

​

Maximum Recommended Dose:

​

• Do not exceed 25 ml per 100 litres of aquarium volume per day. If you need to dose more than 25ml per 100 litres per day, we recommend our H2P dosing system as it will be more effective and economical!

​

Important Notes:

In some systems, calcium and alkalinity may be consumed at slightly different rates due to biological activity and coral demand. If you notice any imbalance, use our  individual Reef Zlements products to fine-tune the parameters.
