what insufficiency make the eggs white ?

[Md. Shafiqual Alam]

I have few proven pairs those had been giving good amount of fry. but couple of months most of the eggs from multiple pairs becoming white by 48hrs. What might be the reason ?

FYI,

Water= TDS 10~20ppm (RO) (Digital meter)
Temp= 29~31c (normal weather temp)
PH= 6.5~7 (Digital meter)
Nitrites= 0 (API test)
Nitrate= 0 (API test)
Amonnia= 0 (API test)
WC= 95% everyday with exact same quality processed & aged water.
Feed= Tertra bits 2 times (1pm & 8pm), BH (9am)

I do not do WC After egg until free swimmer and use MB after 3hrs of egg.

All the proven pairs are giving very frequent and good amount of eggs but turns white. Can any body suggest how to increase the success rate?

Male may be just going through the motion and not fertilizing the eggs. But if it's happening to all at the same time, might be a water issue.

Is there a lot of circulation in the tank?

have you tested calcium and TDS?

oops I see your tds reading. it may be just that the eggs are unfertile and therefore dying

Too much water circulation? If not, male just isn't doing the job.

Unlikely to have that much. Mine had over 900gph in a 75gal they seem to fertilize no problem.
