What is the PH and GH of Chicago water? Joliet water is like liquid rock and I have to use RO for crystals. I tried keeping them in tap and never had any luck with breeding. Then Joliet would add something to the water and I would have a big die off. How big is your tank? RO water is pretty cheap at Jewel in the machines that fill up the 5 gallon water cooler jugs.
Just to clarify, I never say I breed my CRS in tap water. I tried but they won't breed. For OEBT, yes, I keep and breed them in 100% tap water, not a single drop of RO. My tap water TDS ranges from 300 - 360 ppm.
