Math was never my strong suit....

Hey everyone,
I have a 25 gallon cube, AIO, with ~30 lbs of live rock.
1) How many gallons of water do I have? I need to start dosing Mag.
2) How many ml should I dose to raise it 50(ish) ppm per day? (I think I need to know #1 first)

If anyone could help me with formulas, that would be AHmazing :)
Thanks in advance!!

Also my mag is 1450 right now

If mag is 1450 why do you want to dose it?
Recommended number are 1200 -1400 and seawater is about 1280
