| 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. |

Works great!
Just awesome. My water comes out with 0 dKH and 8.2 PH and I inject CO2. With such soft water, my PH would likely be very unstable and crash once my CO2 kicks in. I use this in conjunction with Alkaline Buffer with every water change to lower the PH to 7-7.2 and raise my KH up to 6 to 8. I recommend these over other products because these are not phosphate based. That is especially important if you have a planted tank with lots of light because otherwise you'll trigger an algae bloom very quickly. Given that you only need up to half a tablespoon at most to treat a standard 3-5 gallon bucket when changing water, one of these 600 gram containers will last you several months to a year depending on how big your aquarium is and how often you change your water. It's definitely worth the purchase if you have tricky water like mine.

Lid was cracked and powdered acid spilled. Other than that it works. 47 rules!!

Works
Very functional acid buffer. I was struggling to get my Santa Barbara basic tap water to neutral with PH up products, but with this acid buffer, I just drop in a few granules per gallon, and the ph promptly drops from almost 8 to the high 6, low 7s. I use this buffer to prepare my aquarium water for a 50 gallon tank, and a 15 gallon tank, and I have had 0 fish losses in over 3 months of using the product.

Works, but not really sure the purpose of it
Drops my KH down in my water but doesn't really change the PH. I mix it with alkaline buffer but the chart on the back doesn't really seem to hold true.

Using it to slowly lower kh. Works

Instant Results
This stuff is amazing! I use their other products and I decided to start making Betta water instead of going to my specialty pet store. Knowing my fish water was safe made me feel good, but I decided it was time to save money and make my own. They let me know what I needed. My tap water has a pH of 8.6 and I need a 7.6 or less. So I bought this and added 1/16 or so to my 5 gallons of water I was treating. It worked instantly and brought it down to 7.4. I could not be happier!

Works but use with caution
The product does what it’s meant to do. Lower and/or remove KH. I keep a high end planted shrimp tank so low KH is important. A note of caution. Do not let the bits fall on your plants. It will burn them. Completely dissolve the salt in a glass not plastic cup as it does have some reaction. My plastic cup was clear and has since been cloudy white even after washing it with soap. I can’t dock the product stars since it technically works, but wish I knew some of these things before hand.

Acid Buffer works quite well, mainly because converts the KH into Co2.
