Buffing Alk

[Bucrob]

I have a Water box 130.4 so it's about 126g, alkalinity is 7.6, want it around 8.5. I'm using Red Sea Reef Foundation B Liquid. Mag is 1450 range and calcium is 450 range so no need for A4R. How much of it should I dose? I've dosed around 20mL's over the past 2 weeks and it's gone down by .1 from 7.7. It's probably being consumed by the cycle (tank's fairly new but I have a similar size tank around 90g that also has minimal coral, was FOWLR originally, and also has issues with alk) because I only have a single hammer in there and a blasto, both small frags along with a zoa frag and green hairy mushroom. My LFS salt naturally mixes low on alk around 7.0 to give better trace elements but I eventually plan on making my own salt.

"Liquid supplement: 1ml will raise the Alk level of 100 liters (25 gal) by 0.036 meq/l (0.1dKH)"

so 45.36 ml will raise 126 gal by 0.9 dKH
