Description

Seachem Replenish 500mL — General Hardness (GH) Re-Mineralizer for RO Water Restoring Balanced Mineral Levels to Keep Aquatic Life Healthy In Tanks

Seachem Replenish 500mL (SKU: 725155-1473) is a liquid blend of essential minerals designed to restore General Hardness (GH) in soft or purified reverse osmosis (RO/DI) water. Reverse osmosis filtration removes harmful contaminants alongside beneficial minerals like calcium and magnesium. Reusing unmineralized RO water causes osmotic shock, tissue degradation, and shell/bone softening in fish and invertebrates. Replenish restores balanced mineral levels to keep aquatic life healthy.

Formulated with a balanced ratio of calcium chloride and magnesium chloride, Replenish increases total dissolved solids and GH without adding unwanted sodium chloride. The 500mL bottle provides convenient, easy-to-dose mineral restoration for freshwater community tanks, planted displays, and invertebrate aquariums.

Usage & Application

When to Use

• RO/DI Water Conditioning: Re-mineralises pure reverse osmosis water prior to aquarium addition.
• Preventing Osmotic Shock: Maintains stable general hardness to support healthy osmotic balance.
• Invertebrate Shell Support: Supplies bioavailable calcium required for shrimp exoskeleton moulting.

Dosing & Administration Guide

• Standard Dose: Add 5 mL (1 capful) per 40 L of RO/DI water to raise General Hardness (GH) by 1 meq/L (2.8 dGH).
• Target GH Range: Maintain general hardness between 3 and 6 dGH for softwater tanks, or 6 and 12 dGH for general community tanks.
• Mixing Protocol: Blend thoroughly into fresh top-off or water-change water prior to adding to the aquarium.
