Aqua-pics Ph Down 2kg

Description

Aqua-Pics pH Down 2kg — The largest pack of Aqua-Pics’ granular pH reducer, built for shops and fish rooms

A retailer or a serious hobbyist running dozens of tanks cannot be re-ordering a 200 g tub every fortnight, and the cost per gram only improves once a pack is bought by the kilogram. Aqua-Pics pH Down 2kg (SKU: 724800) is the largest pack in the Aqua-Pics pH Down range, a sodium-biphosphate granular reducer for bringing alkaline freshwater down toward the level soft-water fish need. Aqua-Pics states the formula does not add to algae growth, a relevant point given how much product passes through a system this size over a year. The 2 kg pack suits aquarium shops, large fish rooms and anyone maintaining many soft-water tanks from one supply.

The dosing principle does not change with pack size: there is no single gram-per-litre rate on the label, and Aqua-Pics’ direction is to add it in small amounts as required, never in one large measured dose, because a rapid pH swing is harder on fish than a stable high reading. Once a tank reaches its target pH, Aqua-Pics recommends its own KH Buffer to hold that level, since the carbonate hardness removed by the reducer is what normally resists further pH drift. At this volume, the pack is treated as working stock rather than a single-dose product, kept sealed between uses and measured out tank by tank for soft-water community and breeding set-ups across a whole room of aquariums.

Usage & Application

When to Use

• Shop and wholesale stock: Ongoing pH correction across many display or holding tanks.
• Large fish rooms: Several tanks running on the same hard water supply.
• High-turnover dosing: Systems where pH needs resetting after most water changes.
• Long-term cost efficiency: Buying once rather than repeatedly restocking small packs.

Dosing & Administration Guide

• Measure per tank: Dose from the bulk pack into one aquarium at a time.
• Small, repeated additions: Avoid treating the whole 2 kg as a single large dose for any one tank.
• Retest before redosing: Check pH has settled before adding more to the same tank.
• Follow with KH Buffer: Use once each tank is at its target pH.
