Seachem Acid Buffer

Seachem Acid Buffer is used to lower pH in planted aquariums and convert carbonate alkalinity into available CO2, while being compatible with Alkaline Buffer for precise pH adjustments.

  • Adjusts pH to 5.0—8.0
  • Designed for use in planted aquariums
  • Converts carbonate alkalinity (KH) into available CO2
  • Contains no phosphate

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 the 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™. When using Alkaline Buffer™ & Acid Buffer™ together to target a specific pH, utilize the suggested ratio chart.

HINT: First determine the amount of Alkaline Buffer™ needed for the volume of water. This should be determined based on your desired alkalinity (KH). Then, divide by the number in the middle column to obtain the correct amount of Acid Buffer™ required.

These things are BRIGHT!
Color: 4.5" Combo Light
After watching some videos, I decided to pick up these lights to go on my work truck. I work in a lot of remote locations across CO, WY, and NM. Traveling at night down dark highways and dirt roads can be a little stressful when wildlife is out. Not anymore with these lights! I can easily see anything in the ditches around me and at least 3/4 of a mile ahead of me. I’ve been running them for a few months and have had zero issues out of them. They seem to be super durable, easy to install with all the wiring included, look great on the truck, and you cannot beat the price to performance value. It’s also nice that the include yellow lenses to change the color of the beams for fog. Don’t waste your money on more expensive lights, these will get the job done perfectly for a lot less.
