SEACHEM Acid Buffer 300 GM Auction is for ( 1 ) : SEACHEM Acid Buffer 300 GM Acid Buffer™Adjusts pH to 5.0—8.0Converts alkalinity [KH] to CO2Contains no phosphate Description:Acid Buffer™ is a non–phosphate buffer to lower 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 6.0 and 8.0 when used with Alkaline Buffer™. As Acid Buffer™ lowers pH it converts carbonate alkalinity (KH) into available CO2. Directions:To lower pH, use 1/4 teaspoon (2g) for every 80 L (20 US gallons) daily until desired pH is reached (this dose lowers alkalinity by about 0.2 meq/L (0.6 dKH)). Larger doses may be required in very hard (KH) or alkaline waters. For precise dosing, use the Seachem Digital Spoon Scale. In order to adjust pH gradually, or if water is soft or not well buffered, use Acid Buffer™ with Alkaline Buffer™. PayPal—a service to make fast, easy, and secure payments for your purchases !
