Description
Aqua-Pics General KH Buffer 10kg — Bulk alkaline buffer for wholesale and large-scale dosing
A wholesale aquarium supplier or a large commercial system does not buy a water buffer by the kilogram bag, and a 500 g or 1 kg pack would need constant reordering to keep up. Aqua-Pics General KH Buffer 10kg (SKU: 113129) is the bulk pack of Aqua-Pics’ phosphate-free alkaline buffer, formulated for sensitive set-ups such as planted tanks running CO2, where carbonate hardness needs maintaining at scale without a sudden pH swing anywhere in the system. It slowly raises KH by approximately 1 dKH, or 18 ppm, per standard dose, and being an alkaline buffer with a high pH, it counteracts the acidity CO2 introduces, stabilising pH and reducing stress on fish. It suits both freshwater and saltwater aquariums.
The standard dose is 1 level teaspoon, or 5 g, per 60 L of water, raising KH by about 1 dKH (18 ppm) and helping raise and stabilise pH at the same time. In CO2-injected planted tanks, Aqua-Pics’ directions call for small, cautious doses rather than one large addition, since the alkalinity can push pH up faster than fish and plants adjust to. At 5 g per dose, the 10 kg pack holds about 2,000 doses, enough to raise roughly 120,000 L of aquarium water by 1 dKH over the pack’s life, which suits a wholesale supplier, large retail holding system or commercial-scale operation buffering water across many systems. The same buffer is also sold in 150 g, 250 g, 500 g, 1 kg and 4.5 kg packs for smaller operations.
Usage & Application
When to Use
- Wholesale and commercial systems: Large-volume buffering across many tanks or holding systems.
- Retailers and importers: Routine KH maintenance on display and quarantine systems at scale.
- Large aquaculture or pond operations: Where a kilogram pack would still require frequent reordering.
- CO2-injected systems: Counteracting the acidity that gas injection introduces across multiple tanks.
Dosing & Administration Guide
- Standard dose: 1 level teaspoon, or 5 g, per 60 L of water.
- Expected effect: Raises KH by about 1 dKH (18 ppm) per dose.
- Dose cautiously under CO2: Small additions avoid a large pH increase in any one system.
- Weigh rather than scoop at scale: Measure by weight for consistent dosing across large volumes.
