So I've been reading more and more on fish that people have tried breeding and fail at 1-20 days. I've noticed a lot of breeders logs that never cover the water quality or element levels. I understand that the general view of fish is that you don't need to worry about you trace levels or Cal, Mag, Iod, and so on. These have only been taken into consideration when keeping corals or VERY picky fish. I see a lot of breeders using cheap brands of salt that are not even balanced. My thought is that the developmental stages of fry are just as sensitive to these levels as the coral are. I honestly think that this could be a major factor in the success rate. Any input?
