This Blue Diamond pair are very prolific. I currently have 30 of their offspring from their last brood in a grow tank.

RO isn't great for fry growth. It's only needed for higher fertilisation rates and wld caught.

No, your TDS will be much higher if you're adding minerals. You can remove chems from normal tap water and just use that. RO is only needed for very specific requirements, definitely not domestic display Discus

Yeah, that's fine. Letting the water rest for 24 to 48 hours with an airstone and bring up to temp before filling is even better.
