When TA was 60, pH would go from 7.3 to 8.0 in 1 week. At TA of 50, it goes from 7.3 to 8.0 in two weeks. I'm planning on bringing TA down to 40 to try to stabilize pH even more. But now I'm concerned about CSI.
How high can/should I raise CH to keep CSI above -0.6? Is there another way to keep CSI up?
Then with winter coming, as the temp drops, what's the best way to keep CSI above -0.6?
