i read somewhere that max pH for commons is 7,5....
Full Version: Ph = 8
can a common and a fantail live in "pH=8"??...

Yep, 8.0 is fine. Goldfish can live in a pH of up to 8.5 in fact (any breed). 
pH of 8 is actually a good number. It give you some breathing space in case the pH starts to swing. The nitrogen cycle works better at that pH level as well.
P.S. a word of caution. Ammonia is more toxic at higher pH but if your ammonia is zero then it is not a concern.

Does it? I didn't know that - cool!
Hi Emma,
Yes, it does. It maximum efficiency occurs between 7.2 and 8.3. In fact, the efficiency is only 50% of the max at pH of 7. Drops to 30% at pH of 6.5 and 10% at pH of 6. Of course, there are other factors like temp, O2 level and KH to consider.

That's really handy to know. Thanks!
