Acid Buffer 300gram

If you have high aquarium PH and it keeps bouncing back after using a PH lowering product, try this. It worked for me after bottles of PH Down, salts, and PH neutral powders. You don't need much, but you will see a difference quickly. It does not cloud the water and when added in prescribed amounts has not affected my fish, they are safe. It works pretty quickly, though not as fast as the direct PH Down - but the PH stays down. This is a good value and this brand is a well known supplier you can trust. They also offer a PH Up powder that works in similar, but reverse fashion.

A must for Discus tanks.

Helps keep my ph down.

I've been using this product for years and the fish haven't complained :)

Does what it is supposed to :-)

In its pure form it isn't much of a buffer until you add the basic version as well. Be careful! Measure the pH before you add! I was mindlessly adding this for years till one day I wasn't careful and ended up killing all my koi. It's a great product but seriously read and follow the instructions.

Works, came with a little dent but no biggie

Ooohhh it works. Fast. DO NOT put directly in the tank and DO NOT mix with any other recently added chemicals. As you can tell - I did both and killed 8 of 11 fish within minutes. I was devastated. It was awful to watch and there was nothing I could do. Dropped my pH from 8.0 to lower than 6 almost immediately and the mixed with other chemical and basically my fish suffocated. Read directions and do research. Premix/dilute and let sit for maybe 5min. Potent stuff.
