My Red Severums have spawned recently. This is the second time they spawned and the eggs all turned white. I'm told it probably is because the male is infertile.Also told most male Red Severums are infertile. I read somewhere that hard water could cause the eggs to turn all white with fungus. Is it worth a try to get some water softening pillows and put them in my filters?Or am I just wasting my money on that?Btw PH is 7.0.
