Great Stuff
After initial use ph and hardness have been perfect. Fish showed instant improvement and seem calmer and less aggresive. Plants also showed great improvement.

The best way to control pH and KH
The combination of acid buffer and alkaline buffer is amazing, just as long as you don't read the buffering instructions at the bottom. Those are much too confusing.
Instead, buy a KH test kit (and pH if you want), pick a KH value (4-5 is good for freshwater, but check for your particular livestock), and use these products to reach it. If you dose CO2 it will be more challenging but you'll get there eventually. The reason why is that a stable KH is more important than stable pH and those two are much more important than any given pH value. Setting a specific pH is very very difficult because of the large number of salts in aquarium water, but stabilizing KH will take care of a large percentage of them and give you a pretty good, stable pH. That, again, is much more important than any pH value.
The fact that these are solid makes them easy to dose and a very good value. For liquid products, you pay for water plus a small amount of solid product. In addition, alkaline buffer in particular is very strong - you need only a tiny bit to raise the KH a lot.

Safer to use
I was using Vinegar to get a lower KH. SEACHEM Acid Buffer is safer and easier to use.

Alkaline buffer works best for me
I have two large pieces of driftwood in my freshwater aquarium which release tannins that can lower pH. I have tried many buffers (including African cichlid buffers) to help keep my pH as close to 7.0 as possible. I have found that if pH drops below 6.5, the good bacteria starts to die - which can be a disaster. Combining both Acid and Alkaline buffers seemed too complicated for me. I just use 1/3 to 1/2 teaspoon (for the whole aquarium - not per gallon) of the Alkaline Buffer at a time (depending on my test results - I test pH daily). The most I have needed to add to my 75 gallon aquarium at one time was 1 teaspoon. I like that Alkaline Buffer is phosphate free, too (I use phosphate absorbing resins to remove phosphates). You will have to experiment yourself based on your conditions and local water. Have a reliable pH test kit on hand. Keeping the pH at a consistent level also makes for much happier and healthier fish.
