Description
Quantum Aqua Pro KH 11kg — Trade Pack of KH Buffer Salts for Wholesalers, Farms and Large Ponds
Eleven kilograms of buffer is a wholesaler’s or a pond contractor’s quantity, and Quantum Aqua Pro KH 11kg (SKU: QA431110) is the trade pack of Quantum’s Freshwater Essential Plant Essential Aqua Pro KH. It is the same blend of KH buffer salts as the small packs, formulated to raise carbonate hardness gently and improve pH stability across every kind of freshwater system, from a shop’s community racks to a koi pond of tens of thousands of litres. Regulated KH keeps pH from fluctuating and protects the biochemistry of everything living in the water.
The rate is 5 g, one level scoop, per 100 L for a rise of about 1.4 dKH. At this scale the powder is dissolved in a drum of system water and pumped or poured into the strongest flow; it is never added dry. Only replacement water is dosed at a change, not evaporation. Targets range from 0.5 dKH for South American water to 12 dKH for Tanganyika, with koi at 2 to 4. The 11 kg pack is about 2,200 scoops; raising a 20,000 L koi pond by 1.4 dKH takes 1 kg, so one pack covers the fill and a season of post-rain corrections.
