And just to clarify hilde are you saying that if i wish to keep same a pair of blue rams that prefer water between 5.0 -7.0 and my tap water is say around 7.8 that it is better to just put them in and let them sort it out???
After having lost a gold RAM and gold Apistogrammi, which both need low PH, I wouldn't get any. The gold seem to be more sensitive, though. If they are raised with high tap water they would be okay, so I have been told.
