Maintaining Ph during hyposalinity

What's the best way to do this? I am at the 36 hour mark and about to drop the salinity from 1.015 down to 1.013. Current ph is 7.85 as I have yet to make any corrections. I have baking soda, limewater mixed at 75% saturation and b-ionic two part to choose from. I would like to make the correction up to around 8.0 at the same time I drip the next addition of fresh water in. My water voume is 9 gallons and I am doing 1.5 gallon replacements.
Thanks in advance.

Link me to a ph calculator please!

I used Seachem Reef Buffer when I did it. It worked great.

I never worried about it. The pH drop and increase is slow just as the SG. I've never had a problem.

A simple mix of baking soda and washing soda is what I've used. Do a search on buffer and you'll find the right ratio. I think it's about 4:1, but don't quote me on that.

I ended up using 1oz lime water to a gallon of RO to get 8.3ph.

I just used PH up drops. It seemed to work fine and required very little work.
