Alkaline Buffer™ is a non-phosphate buffer designed to raise pH and alkalinity (KH) and buffer with Acid Buffer™. These buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem. Alkaline Buffer™ raises pH and buffers between 7.2 and 8.5. It is gentle, safe, and enhances the freshwater environment.
Why It’s Different
What distinguishes Alkaline Buffer™ from other buffers is that it does not contain phosphates. This makes it ideal for the planted aquarium, where excess phosphate could contribute to undesirable algae growth.
Use 7 g (1 level teaspoon) for every 40 L (10 gallons*) daily until desired pH is reached (this dose raises alkalinity by about 2 meq/L (5.6 dKH)). If water is soft or not well buffered, use with Acid Buffer™ (see below). HINTS: Alkaline Buffer™ will not lower pH. It may be added directly to the aquarium at any time. It preferentially buffers at pH 7.8, but can manage any pH between 7.2 and 8.5 when used with Acid Buffer™.
|Acid Buffer||Alkaline Buffer||pH|
If using with RO or DI water for a water change, then use with Acid Buffer ™ at a fixed ratio (see chart) to set the desired pH. Once pH is set add water to aquarium as soon as possible to avoid pH fluctuations (for best results, base ratio on weight of product added).
