Artificial hatching - water changes before eggs hatch?

[GeauxDiscus]

I am trying artificial rearing, and I currently have the eggs separated from the parents in a little 5 gallon tank. As long as I'm aerating, is it necessary to change the water before the eggs hatch? It wouldn't seem like the eggs would produce any waste.

I keep egg in 1 gallon and i do 30 to 50% just before they hatch

I usually use 100 percent RO with added acriflavine or MB in a small container. Waterchange into GAC water just before hatching to get out the MB or acriflavine and decaying of the unhatched eggs.
