Seachem Marine Buffer 50g – Marine Aquarium pH Stabiliser (8.3)

Seachem Marine Buffer 50g is a scientifically formulated marine pH buffer designed to safely raise and stabilise saltwater aquarium pH at 8.3. Unlike simple carbonate or bicarbonate products, Marine Buffer uses a unique blended formula that prevents dangerous pH spikes, even if accidentally overdosed.
