Discus Buffer 250g

This powder is for discus keepers who start from soft, unbuffered water such as RO or DI and need a stable pH in the tank. Its main job is to bind calcium and magnesium, so the water stays soft and the pH can be set to a target value.

Why it matters

• Softens the water: it precipitates calcium and magnesium ions, which lowers the hardness of the water.
• Sets the pH: used with Neutral Regulator, it gives a defined pH value depending on the ratio of the two products. The table starts at 6.8 for a 1:1 ratio and falls to 5.8 for a 1:9 ratio.
• Works during water changes: the supplier describes use during water changes and top-ups of evaporated water, which keeps the pH consistent between maintenance steps.
• Needs a trace element supplement: the supplier recommends Discus Trace to keep the trace elements that discus need for healthy development.

What it works with

The product suits discus aquariums in the 40–80 L range per daily dose, set up on unbuffered RO or DI water. The supplier notes that if a buffer has already been added to the water, the chart values should be treated only as a starting guide. It is used together with Neutral Regulator when the pH needs to be raised.
