This works where others don't! Problem PH too high? Use this!
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.

MAKE SURE TO MATCH WITH THE BASE
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.

Great, but know how to use
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.

Il prodotto è stato molto utile e particolarmente efficace per abbassare il KH nel mio acquario che,pur facendo dei tagli d'acqua osmotica, non riuscivo a stabilizzare al valore desiderato. Attenzione a non esagerare, io ho dosato gradualmente (bilanciando in modo più preciso con Alkalin buffer) fino ad ottenere il valore più consono per la tipologia di pesci che dovevo inserire nell'acquario stesso. Ottimo prodotto.

I bought this to solve a pH issue in my goldfish aquarium. It performed better than any other pH adjuster i have ever used. Results were repeatable and consistent. I'm no chemist but I do know this changes the pH in a much more natural and gentle way than the harsher normal chemicals generally used. It isn't cheap but I will definitely be using this exclusively from now forward. A little goes a long way so even though more expensive, considering all the above I';d say it is good value overall. Very happy with this one, Seachem, rarely disappoints. HIGHLY RECOMMENDED.
