Good morning, I just left my LFS and was advised that i need to raise my PH. I bought Kent Superbuffer - dKH and the instructions are unclear to me. I have a 72 gallon Bowfront and a 20 gallon fuge. (10 more gallons of water) I'm not sure how much to add to the sump to slowly raise the PH. Current PH range is 7.9 and per my LFS need to get it to 8.2 to 8.3. Thanks in advance for all the support you guys help me with.
