Hallo!
You are talking here about how to get the lowest pH… 🙂 … I know, that Paros at home have very low pH…but down from 4 pH on I mean to have read its also for Paros stress …
From what pH down will it be dangerous?
My prepared Paro tank has already about 4,7 pH , conductivity 50, in the morning (in the evening pH even will be lower, am I right?
In my wild cought Spaerichtys selatanensis tank I have already 5,3 pH with conductivity of 97.
Who can say from what pH it begins to become dangerous also in black water?
By the way, I´m really a bit shocked that I´ve found out now, that almost all of my other fish (L333, Boraras brigittae, corydoras pygmae) all are black water fish .. in the internet or in books you have to search long to find further informations than kH, temperature, size of tank …..
Concerning this, at the moment the best information I got in my aquaristic shop was about the spaerichtys selatanensis …
Perhaps the shops are afraid to tell about black water, because the wouldn’t sell so much fish than …
Informations about the african fish (high calcium) and sea water perhaps are more better … but I don’t know much of them.
