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
