Aqua-pics African Kh Buffer 600g

Description

Aqua-Pics African KH Buffer 600g — Firm pH 8.5 buffer for established Rift Lake tanks

An established Rift Lake tank that has been drifting slightly acidic for months needs more than a token pinch of buffer to pull pH back to 8.5 and hold it there. Aqua-Pics African KH Buffer 600g (SKU: 101610) is a phosphate-free mineral buffer from Aqua-Pics (Australia) with a stronger dose rate built in specifically to settle pH near 8.5, alongside a gentler rate for routine top-ups. It raises carbonate hardness (KH), which resists pH movement rather than adjusting the number only temporarily, and the maker also credits the blend with supporting fish fertility and egg production. The 600 g size suits an established single tank running regular water changes well into its second year, not a short trial.

At the stronger rate, 5 g (1 level tsp) per 20 L, KH climbs to about 12 dKH (214 ppm) and pH settles near 8.5; halving the concentration to 5 g per 40 L gives a gentler 6 dKH (106 ppm) lift for routine maintenance. A 600 g tub treats about 2,400 L run entirely at the stronger, pH-8.5 rate, or about 4,800 L spread across lighter top-up doses. It is the midpoint of eight sizes, between the 300 g tub and the 1 kg pack.

Usage & Application

When to Use

• Established tanks drifting acidic: Use the stronger dose to pull pH back to 8.5 and hold it.
• Routine maintenance doses: The gentle rate restores KH without overcorrecting pH.
• Mixed dosing schedules: Alternate strengths depending on how far pH has drifted since the last change.
• Breeding tanks: The blend is also said to support fertility and egg production.

Mixing & Application Guide

• Stronger rate: 5 g per 20 L for about 12 dKH (214 ppm), pH near 8.5.
• Gentle rate: 5 g per 40 L for about 6 dKH (106 ppm).
• Test before dosing: Check current pH and KH to decide which rate the tank needs.
• Dissolve first: Mix the measured dose into tank water before adding it, never dry.
