I also have moderately hard water, 250ppm gh and 7.8 PH. And this is after mixing in 50% RO. Surprising that they would spawn after adding salt to the water. Maybe just the change sparked something.
I have had Rams spawn in my water but never viable eggs. Would be quite a shock if these egg somehow hatched.
