What is an acceptable amount of ph fluctuation for a typical day cycle?  I am not currently having any specific issues just wondering and wanting to be proactive.

Here is a chart from a few days for my tank.



I have a 90G tank with a 20G sump.  I am running reverse daylight with Chaeto.  I am dosing a 2-part daily, that's what the jump and then slight drop in ph is every morning.

Lighting - 6 retrofit T-5's

Current Water Parameters:
Ammonia - 0
Nitrite - 0
Nitrate - 0
Phosphate - 0
Alk - 8.6
Calcium - 400
Magnesium - 1290
SG - 1.024
Temp - 78
