Quantum Amazon River Ph Buffer – 500ml

Description

Quantum Amazon River pH Buffer 500ml — Weekly pH Regulation for Discus and Amazon Community Aquariums

A 300 L Amazon tank dosed weekly gets six months from a 500 mL bottle, which is why this is the size most soft-water keepers end up buying. Quantum Amazon River pH Buffer 500ml (SKU: QA330500) is Quantum’s Amazon River pH Pro, a solution of safe pH buffer salts in deionised water that regulates pH to replicate the slightly acidic rivers Amazon fish come from. A tank whose KH and pH are not regulated is prone to swings, and swings disrupt the biochemistry the fish depend on. The bottle is meant to be used with Amazon River KH Pro and Amazon River Pro Salt GH, over a slightly acidic substrate.

Ten millilitres per 100 L once a week, or as required, holds pH between 6.3 and 6.7, and Quantum positions the product as a maintenance supplement. Only the replacement water is dosed when a change is done. On a 300 L discus tank that is 30 mL a week and roughly sixteen weeks from the bottle at the full weekly rate; tanks that only need it every second week stretch that further. Because pH in soft water responds quickly, testing before each dose and adjusting the interval is better practice than dosing on the same day regardless.

Usage & Application

When to Use

• Mid-sized Amazon tanks: Discus, angelfish and tetra communities of 200 to 400 L.
• Breeding set-ups: Apistogramma and discus pairs conditioned in acidic water.
• Tap water above neutral: Homes whose supply pulls the tank’s pH upward at every change.
• Blackwater biotopes: Tannin tanks where the keeper wants pH held in a defined band.

Dosing & Administration Guide

• 10 mL per 100 L weekly: Or as required, to keep pH within 6.3 to 6.7.
• Test, then dose: Let the reading set the interval, which may be longer than a week in a stable tank.
• Change water only: Dose the replacement volume at a water change, not the whole tank.
• Complete the set: Amazon River KH Pro and Pro Salt GH handle KH and GH alongside.
