Sodium Bicarbonate (Baking Soda)

Sodium Bicarbonate (Baking Soda) – Pond Water Treatment

Food-grade Sodium Bicarbonate (Baking Soda) for use as a safe, effective pond water buffer. Raises and stabilises KH (carbonate hardness) to prevent dangerous pH swings that can stress or kill Koi and other pond fish.

Key Features

• Raises KH (carbonate hardness) – increases the pond water's buffering capacity to stabilise pH.
• Prevents pH crashes – low KH allows pH to drop dangerously overnight, causing fish stress and mortality.
• Safe for fish and plants – a natural, food-grade mineral with no harmful residues.
• Easy to dose – dissolve in a bucket of pond water before adding.
• Essential for Koi pond management – particularly important in established ponds with heavy bioload.

Specs

• Type: Pond water treatment (KH buffer)
• Active: Sodium Bicarbonate (NaHCO3)
• Brand: Nishikigoi

How to Use

Target KH: 100–200 ppm. Dissolve in a bucket of pond water and distribute evenly. Test KH before and after treatment. Add gradually to avoid rapid pH swings. 1g raises KH by approximately 0.6 ppm per 1,000L. Contact us for a dosing calculation for your pond volume.
