Yup, depends on tank. My dKH usage is 3.5/day and I test every couple days. The slightest change in the reactor effluent ccan have a significant impact on my dKH.

I target 7.8-8.0 and have found that a shift of .5 per day does not have much impact on my coral, but if it swings back and forth I will get some RTN
