CRS in high tech tank

[Ivan Stoyanov]

I'm going to try to introduce CRS in my high tech planrlted tank. My kh is 0.5 and I run around 5.7 ph during light period. I know shrimps not like ph swings, so I'm thinking to run my co2 24/7. The problem is that I'm not sure which levels of ph to do constantly. Can someone that has experience with CRS in high tech tank to tell me what is better to do co2 24 hours or maybe ph swing of 1.2 point won't be harmful for the shrimps.
Thanks in advance

My tank runs with an 8hr photo period and a 8hr co2 period. My CRS are breeding and have done fine.
