The one pair that's already spawned for me, the female is yellow every morning. I will probably do another change tonight with RO on them to drop them from about 120 down to the 50ish range TDS. I'd like to prove that they can breed period before I start seeing how hard they can go. I guess I should have taken a bit more water out last night, but that's OK. Hoping to pick up another bigger barrel on Friday so that I have more flexability with RO. Right now I just have a 32 gallon trash can and it's partially full, so I'm worried if I leave it on when I go to work for 10+ hours that I'll come back to it spilling "valuable" water on the floor.
I haven't set up my solenoids yet, when I do that I'll be able to turn the RO on/off from my phone (or automatically, once I know about how long I should leave it on the fill the barrrel mostly).
