Seachem Alkaline Buffer

Seachem Alkaline Buffer is used to raise pH and alkalinity in planted aquariums, adjusting pH to a range of 7.2 to 8.5 without adding phosphates.

  • Adjusts pH to 7.2—8.5
  • Designed for use in planted aquariums
  • Increases alkalinity
  • Contains no phosphate

Alkaline Buffer™ is a non–phosphate buffer 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, and safe, and enhances the freshwater environment.

To increase pH, use 1 teaspoon (6 g) for every 80 L (20 US gallons) daily until the desired pH is reached (this dose raises alkalinity by about 1 meq/L (2.8 dKH)). For precise dosing, use the Seachem Digital Spoon Scale.

In order to adjust pH gradually, use Alkaline Buffer™ with Acid 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.

Buy these! Theyre my new favorite! Get two! Three? Four? Leave some for me!
Size: 8, Color: Egret/Lavender/Multi
Okay im absolutely freaking obsessed with these shoes! These are so darn comfortable AND cute! Im going to be buying only these for sandals from here on out. Im short, like 5 ft. I like that these give me a little height, but while also being so stupid comfortable that I can wear them legit all day long. I have arthritis and my feet tend to swell if im not comfortable. So these are my new favorite shoe for sure!

Ehh they’re cute and cheap so I’m good with it
Almost hard to walk in because they’re so squishy. But they’re comfy and cute. Just takes some getting used to. I think the quality is pretty good considering I paid $20.

Very pleased with these!
Size: 9, Color: Egret/Lavender/Multi
I wasn't sure about these, but have had good luck with other HEYDUDE shoes. So I ordered these. True to size. I'm pleasantly surprised. Very comfortable and cute. They don't look like the usual HEYDUDE frumpy shoes. But yet they provide the same comfort as frumpy HEYDUDES. (Nothing against frumpy HEYDUDES. I own a pair and wear them for comfort.)

Runs large and too squishy of a sole
Size: 9, Color: Black/White
Why did you pick this product vs others?: I really wanted to love these, but the fit was off, and the sole is extremely squishy, which on a platform shoe was nearly a disaster.  I wear an 8.5/9 in all my shoes. I got a size 9, and they were far too big. I also have wide feet and the straps still had excess room between the strap and the tops of my feet.  I tried the shoes on, took a few steps, and the sole was so squishy it felt like I was falling. If I had a size 8, instead of 9, maybe that would not have happened.  I ended up returning, but wish the fit was better as these are super cute shoes
