Seachem Discus Buffer

pH Reducer and Water Softener for Discus Fish

Product Overview

Discus Buffer™ is a powder specifically formulated to lower pH levels to a range of 5.8–6.8 and help simulate the ideal environment for Discus fish (which require low-pH and low-GH water). The product lowers and maintains low pH levels while softening the water by precipitating calcium and magnesium. It contains phosphate buffers and conditioning agents and is safe for all freshwater fish adapted to acidic water conditions.

It lowers pH to the 5.8–6.8 range and allows for precise control when combined with Neutral Regulator™ to achieve a specific pH value in unbuffered water (such as RO water).

Primary Uses

Safely lowering pH to the desired range (5.8–6.8).

Helping Discus aquariums simulate their ideal natural environment (low pH and low GH).

Softening water by precipitating calcium and magnesium.

Precise acidity control when used with Neutral Regulator™ in specific ratios.

Suitable for use with Reverse Osmosis (RO) water or water with low alkalinity.

Benefits and Features

Creates an ideal, healthy environment for Discus fish and similar species.

Lowers pH and maintains stability at the desired level.

Reduces General Hardness (GH) by precipitating the mineral salts that cause hardness. Completely safe for freshwater fish adapted to acidic environments.

Allows for precise pH adjustment when combined with Neutral Regulator™.

Directions

To lower pH

Add:

One level teaspoon (5 g) per 40–80 L (10–20 US gallons) of aquarium water daily

until the desired pH is reached.

Thereafter, use once a month or during water changes as needed to maintain the pH level.

For precise measurement, the Seachem Digital Spoon Scale is recommended.

To precisely adjust pH using Neutral Regulator™

Use Discus Buffer™ with Neutral Regulator™ in specific ratios to achieve a target pH (assumes the use of RO water or water with no carbonate buffering).

Ratio examples (Neutral Regulator : Discus Buffer):

pH 6.8 → 1:1 ratio

pH 6.4 → 1:2 ratio

pH 6.2 → 1:3 ratio

pH 6.1 → 1:4 ratio

pH 6.0 → 1:6 ratio

pH 5.8 → 1:9 ratio

Important Notes

Dosage is determined by the target pH value.

It is recommended to use Discus Trace™ to replenish appropriate trace elements after softening the water, and to feed fish NutriDiet® Discus Flakes to ensure their health and vitality.

Use Prime® to dechlorinate tap water before performing water changes.

If using pre-buffered water, the charts serve only as an initial guide.
