Thank you for your responses. I have been mixing 75% rainwater to 25% tap water to be close to my desired TDS level. With my Hanna meter, I can closely monitor my exact numbers. My cyanostictum SAM have clearly not been told their TDS is too high, they are still spawning at 125 PPM TDS levels. Abacinum seem a little more reluctant though.
