Acid Buffer - 10.6 oz.

Acid Buffer is a non-phosphate buffer that lowers pH and buffer with Alkaline Buffer. Both buffers are designed for the planted aquarium or for very hard water, where phosphate buffers may pose an algae or cloudiness problem. Acid buffer lowers pH and buffers between 5.0 and 8.0 when used with Alkaline Buffer. As Acid Buffer lowers pH it converts carbonate alkalinity (kH) into available CO2. Treats up to 3,000 gallons of water.

Contains: Proprietary powdered nonphosphate buffer salt.

Directions: To lower pH, use 2 g (1?4 teaspoon) to every 80 L (20 gallons*) daily until intended pH is reached (this dose lowers alkalinity by about 0.2 meq/L (0.6 dKH)). Best if added directly to aquarium. If water is soft or not well buffered, use with Alkaline Buffer. TIPS: Larger doses may be required in very hard (KH) alkaline waters.

If using with RO or DI water for a water change, then use with Alkaline Buffer at a fixed ratio 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).Use these ratios to target pH:

Acid Buffer : Alkaline Buffer
1 : 0.5: 5.0 pH
1 : 1.0: 6.0 pH
1 : 1.3: 6.5 pH
1 : 2.0: 7.0 pH
1 : 2.5: 7.5 pH
1 : 4.0: 8.0 pH
