Three Core+ daily-dose packets
One each of Core+ Alkalinity (carbonate system), Core+ Calcium, and Core+ Magnesium. Each packet dissolves into 1 L of RO/DI water to make stock solution. Pre-measured on calibrated balances, sealed in food-grade aluminum pouches with oxygen absorbers and desiccants. Every batch independently ICP-verified at Reef Labs.
Three reusable 1 L mixing bottles
Color-coded by chemistry — red for alkalinity, green for calcium, blue for magnesium. Built to last. One bottle per chemistry, refilled by mixing a fresh packet whenever your stock runs low (typically every 30 days for a mixed reef).
One graduated 1 L mixing beaker
For mixing stock solution from packet to bottle. Graduations from 100 mL to 1,000 mL. Reusable across every refill.
Precision dosing adapter
Threads onto your stock bottles for mL-accurate daily dosing — by hand or paired with any dosing pump.
QR-coded batch verification
Every packet's label carries a QR code linking to the full ICP-OES report for that exact batch. Scan and verify what's actually in your chemistry — element by element, lot by lot.
