Buen producto
Utilizo el producto desde hace años. Funciona bien. Ayuda a tener el kH exacto , añadiendolo al agua de osmosis. Recomiendo añadir tambien simultaneamente sales que suban el GH , el producto se llama balance.

Best if used w/acid buffer - Great for raising pH and KH
My tap water has very low KH, so I needed something to raise it to keep my tank from major pH fluctuations, such as from my new driftwood. If you are trying to hit a specific pH, you would do well to buy the Seachem acid buffer with this alkaline buffer and mix them with a specific ratio per the instructions on the container. I had just gotten a nice large piece of wood for my tank, and didn't have the time/space to soak it separately, so I put it directly in my tank. To keep the initial wood rot and tannins from lowering my pH significantly, I got this alkaline buffer, in addition to some activated carbon. I added just enough to raise my KH to about 4 degrees and the pH to about 7.4, which is where it was before the tannins started lowering it. pH has now stabilized to around 7.3-7.4. With tank cleaning/water changes, more buffer will eventually need to be added to keep things stable. It seems to be a decent product, and was very cheap, so I'm happy.
