I want to delay the weekly 20% (nitrAte-removing) water change, as my Dwarf Gourami have been mating/laying eggs today. I think the floating plants which currently hold the egg-filled bubble nest will break apart as the water level drops, and I'll lose the falling eggs to my Glowlights/Corys...
...How long will it take for the eggs to hatch? i.e. how long is it safe to delay the partial water change? What is the maximum 'safe' Nitr'A'te level before a water change 'must' be done?
My current readings (7 days since the last partial water change) are: Ammonia and Nitr'I'tes '0'... Nitr'A'tes at 20mg/l...
