What's your current PH? I'm not going to say CRS won't survive/breed in high PH because there are successful cases, but I'll tell you my eco-complete raises my PH from 7.6 (tap) to 8.0+, even after 10 months. Not everyone has this issue so it might be different depending on the batch you get. Perfect for my PFRs though, they keep breeding in the tank.
