Just a thought,
To cut down on the time,You should know what your tank average was/is for a couple weeks prior. Then boost (gradually) to the numbers you want to maintain by turbo calcium and kh hardness(reef builder carbonate or the like).Magnesium Then...........and only then......This will solve the geussing problem.
Watch how much the tank uses (values will drop off) over a set time interval like three days(meanig YOU DONT ADD anything just watch) , then re test (make sure your right ,do it twice if need be) divide by three and that is your target amount
you need to maintain every day(granted as things grow out the values will change).
NOW....... you can adjust amounts through keeping notes as you will have valid info to base usage amounts on...This is where rereading the bottle instruction will make sense....Do what it says for the amounts you need......
Watch and maintain records on them all(dont' forget to hold Mag. at 1325 or so or its all out the window).
This will give you enough to get a very close first time dose then dial it in over time.....
Keep posting if you need to hear it a different way till someone makes it click for you...
Hope this
