SeaChem Marine Buffer

Safely raise the pH to 8.3 without having to worry about overdosing. It is a blended formula that contains sodium, magnesium, calcium, strontium, and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate. The combination of elements instead of not just sodium bicarbonate or sodium carbonate can prevent raising pH to dangerously high levels if overdosed.
