Seachem Acid Buffer 300gram

Make sure you use this in unison with alkaline buffer to keep your fish safe.

I learned the hard way not to chase ph anymore if I want my fish alive. Had 18 guppies, now I have 3 left. Had 6 neon tetras... all gone. Most of my 41 fish made it but lost 15 guppies and 6 neon tetras... I used acid buffer and alkaline buffer and followed the instructions. Just don’t do it. I have a 60gallon tank. Now I just used filter water and haven’t had a dead fish since then.

Good quality, as described.

Okay I really dont know why I bought this. But as the bottle says its great for plants because it softens the water! My local tap water is 0 kh and 0gh. I wasted my money but I guess Ill use it when I move somewhere else

Great product

I tried almost everything out there, from peat granules and driftwood to the proper API chemicals, to lower the pH of my local tap water (dGH: 15, dKH: 6, pH: 7.8). pH DOWN from API was good but not good enough, the dose said two drops per gallon but that wasnt nearly enough. I had to quadruple the dose and it only went from a 7.8 to around 7.1 just for it to bounce back to 7.8 the next day. Acid buffer keeps the water acidic and I only had to double dose the first week. My aquarium water is pretty well buffered now and it doesnt bounce back after every water change. Pretty great product from Seachem. 5/5 would recommend.

Used the product per instruction and I found a couple healthy big neon tetras (1 inch +) died next couple days after the application. After I stopped using the product and did 50% water changes, the fish stopped dying. No news about my return. Very frustrating.

Little tricky to figure out the correct amount at first, but after that this was great!

Love it

In my own tank at home I am raising some South American Cichlids (specifically Heros Severus, common name Severums), and where I live I have well water that runs through a natural Calcium Carbonate surface that causes the pH coming out of my tap to be at around 8.4. I tried so many different products to lower pH. People recommended a tannin soak which didnt work, a lot of other products only focused on the pH (while neglecting the hardness) and therefore would cause serious fluctuations in the pH. It would drop when the pH decreaser would enter, and than rise back up in 24 hours, and cause a serious stress on my fish. I came across this on accident since none of the close pet stores sell this product. I wandered into a mom and pop fish store in my neighborhood and the guy recommended it to me. I tried initially without really reading the instructions (yeah I admit it) and I wasnt successful. I put the product away for a little while and finally gave it another shot (this time reading the instructions and following them) and it did work. My pH in my aquarium right now is at a 6.4. A few warnings about this product, it is potent stuff. I have dropped the pH too drastically at times while preparing the water in a bucket. You can correct by introducing small amounts of baking soda into the water (or just mixing in some more of your tap water to correct for the low pH). Now I order it online since the mom and pop shop only has a small size of it. I have not tried using the alkaline buffer, but the label states you can obtain set pH values by mixing certain amounts of both alkaline buffer/acid buffer.
