Quantum American/Aust MPMC GH 5L — Bulk Pro Salt GH for Cichlid Breeders and Native Fish Rooms
Native fish breeders and cichlid wholesalers remineralise water by the barrel, and the 5 L container is sized for that. Quantum American/Aust MPMC GH 5L (SKU: QA365000) is the bulk size of Quantum’s American/Australian Pro Salt GH, a solution of major, minor and trace elements in deionised water that raises general hardness gently and in the ratio that replicates American lakes and Australian waterways. Macrobiotics, probiotics and vitamin precursors are part of the formula to promote beneficial bacteria and fish vitality, and it is designed for use alongside American/Australian Buffer Pro for KH and pH.
The rate is 10 mL per 100 L for a rise of 1 dGH, with a recommended range of 2 to 4 dGH, and only the replacement water is dosed during a change. A fish room conditioning 500 L a week from RO water to 3 dGH uses 150 mL, so 5 L lasts around thirty-three weeks; a shop treating a central reservoir for cichlid and native stock gets similar mileage. Since fish take up much of their calcium and magnesium from the water, holding GH steady across every tank supports growth, colour and spawning throughout the room.
Usage & Application
When to Use
- Cichlid and native breeders: Fish rooms remineralising hundreds of litres of change water each week.
- Retail hard-water systems: Shops holding American cichlids and Australian natives.
- Very large displays: Predator and native tanks past 1,000 L on big weekly changes.
- Reservoir treatment: A single container remineralising a mixing tank that supplies a whole rack.
Dosing & Administration Guide
- Set the GH: Between 2 and 4 dGH for the species kept, the same on every tank fed from the reservoir.
- Dose the reservoir: Work out 10 mL per 100 L per 1 dGH on the barrel’s volume, not the tanks’.
- New water only: The dose belongs in the change water; the tanks themselves are already at target.
- Buffer alongside: American/Australian Buffer Pro sets KH and pH to complete the chemistry.
