The pH in my 20 G QT has been running low--scraping 8 or just under. I've read that pH fluctuates a lot in new tanks, so I haven't worried much. But I mixed up some new water yesterday . . . 6 gallons of IO in a covered rubbermaid tub for 24 hours with a maxijet 1200 (using RO water from the grocery store machine). When I checked the pH, it was only 7.95! So it's not the tank lowering the pH, it's the fresh water I'm adding. I thought salt mixes were supposed to have buffers in them . . .? Should I be adding buffer to the fresh water, or to the tank? If to the water, can I add the buffer before storing the mixed SW for a week or more?
Sorry for the spate of questions, but I can see that I need to get a handle on this sooner rather than later. Thanks for any suggestions.
