their wastes are acidic. without a buffer system the pH can drop from a single drop
of acid. actually, most rain water is acidic. GF do very well in 0.1% NaCl. that
is 0.9 lbs per 100 gallon or about 1 tablespoons per 5 gallons, no additives,
dissolve first, add slowly. split addition up over a few days rather than all at
once. Ingrid

Why will the p.H fluctuate? Couldn't I just check the p.H when I top
up the tank ? The change water is coming from a very large rainwater
tank and does not vary much in p.H. Can the fish be acclimitized to
different salt levels? What is the range of their salt tolerance?
