Intresting Wright it is maybe the combination javamoss and acid water
wich gives me the good result with the eggs.Many have problem to get the
javamoss growing espcaly the ones with alkaly water,wich contains wery
low CO2 wich is inportant for the plants.My experaince with salt and
javamoss is the same as yours have one to two teaspons of salt per
gallon in all my tanks.Our feeling is that it is the CaCO3 wich gives
the problems with fertilasion of the eggs.There is studies done in this
and the result was that CaCO3 make the eggshell to "hard" to penitrate
for the malesperms.Free Ca dosent seem to be a problem.
