Part 1: Hybrid Complete/pHplus This vital component consists of two interchangeable solutions, Complete and pHplus, each designed to increase alkalinity and enrich your reef aquarium with a comprehensive blend of macro and trace elements. Each litre contains 10,000dKH units, and a 10 ml dose can raise the alkalinity of 100 litres of water by 1dKH. The two solutions differ in the effect that continuous use will have on the pH of your water. Complete: Ensures optimal alkalinity whilst gently elevating pH. pHplus: Ensures optimal alkalinity whilst actively increasing pH. Custom Blending: Mix Complete with pHplus to tailor the pH balance to your aquarium’s needs. Dose them together or separately for pH adjustment and control. Part 2:Universal Universal is the rebranded Part 2 solution and essential part of the Reef Zlements H2P Dosing System. It contains approximately 72,000 mg/L of Calcium, but also a meticulously balanced blend of 13 essential macro and trace elements, crucial for the health and growth of your corals. Each of the elements plays a critical role in creating a stable and thriving environment for your reef. Simplified Dosing for Exceptional Results Start with a 1:1 ratio between Complete Part 1 and Universal Part 2. Dose in areas of high water-flow for even distribution. Continuously monitor and adjust alkalinity and calcium levels as needed. pH Management Made Easy To raise pH: Increase the proportion of pHplus. To lower pH: Decrease the proportion of pHplus. Make adjustments gradually and monitor the changes. IMPORTANT NOTE: If you don’t monitor your pH, we recommend starting with Complete and Universal.
