Works as intended. Tested water the next day and water was perfect. Good value as only use a tiny bit. Fish appear happy and no deaths. Water remains clear.

Does what it is supposed to
My tap water has a very low KH (1d) and a reasonably high pH (7.5). Because of this the pH can be unstable in my 125 litre community tank. I use the Alkaline Buffer along with the Acid Buffer to raise my KH by 2 or 3 degrees without affecting my pH. The Buffers are easy to use and last for quite a while, depending on what tub size you go for. All of my fish, including the sensitive German Blue Rams, are happy and healthy.

Does what it says on the tub. Essential for low KH areas!
Perfect for raining my KH in my axolotl and planted tanks!

Great price:size ratio
Did the job just make sure to add very little at a time. I did the dose stated and went from 6.5ph to 7.4
