Hello all. I've had my 75 gallon FOWLR up and running for a week now. I have approximately 100 lbs of cured live rock I purchased from a local person's established tank. I have approx. 2 inches of oolitic aragonite sand as substrate. There is a 45 gallon sump with another 20 pounds of Live Rock Rubble for added filtration. Protein Skimmer is an aqua-c Remora Pro located on the sump. Currently Running. Tank is filled with all RO/DI water. Salinity is within normal parameters. Current Known Water Parameters: Ammonia: 0 Nitrites: 0 Nitrates: 0-10 ppm PH: 7.8 I know the ph is at the low end of the acceptable range. My question is this: Should I expect the ph to rise at all on its own, or will I need to use buffering agents? I have checked the ph 3 times, and all 3 readings have been 7.8 Thanks in advance.
