My thread is old I know: Discus fry

pH is not really a big factor in spawns.. more the TDS or gh.

mine spawn readily and with success in a pH 7.0-7.2 but my gh is low (5-6) and kh is 3-4.

using ro or distilled water should lower ther TDs and increase the chances of the eggs being fertilized. provided the parents are viable.
