Best TDS for breeding?

I'm definitely on a slide in my breeding program. Before they switched my neighborhood from city water to county water, my fish were successfully breeding left and right. I thought the TDS reading then was 160ppm, but can't swear that's right.

NOW the TDS in the water supply measures 265ppm. So, I purchased an RO system, and tried breeding them in 120ppm water unsuccessfully. Now I have my proven pairs in 70ppm TDS water, and NO LUCK fertilizing the eggs! Everything else seems to be the same; same pairs, same mating behavior, same food and temps, but eggs always turn white.

Could it be a different water parameter that is interfering? Any suggestions on what to do ? ? ? -Don

Try one batch with Zero TDS and see if it works out.

Don, what's your GH? A GH about 70 ppm should help.

Following as I have almost the same situation.

Don, It could be some mineral,chemical, ect. in the water that is different from your previous supply. You should have your water checked out by the local state extension service. I'm on well water and I have it checked out every 3 years.Very inexpensive and I live in Ct.
Also, what do you mean by "country water"

I am following as well. I am trying peat granules from Floval. In five days my tap water has become perfect for breeding. GH and KH are very low now so I am going to try it with out RO.

Don try what Rick suggested to me pull the eggs out after they are fertilized and put them in a container with distilled water add some meth blue for a couple of hours then tranfer them to another container and see if they hatch , make sure you have air and heated water, if they hatch well you have some water problems,

I know it's the same male, but make sure he's doing the job?
