two part with magnesium

[Zann]

i got a tow part mix from twopartsolutions it came with magnesium
but on the site it says to add all the magnesium after you finish the two part both gal of it .
it will take me a while to use the part one and two gal of each in my 30 and 24 gal tanks.
how should i dose the magnesium ?

Well, if there have been a fair number of water changes, you might not need to dose the magnesium at all. Otherwise, I'd measure the magnesium level, and dose as needed.

i do a water change each week on the 24ap and every two weeks on the 30gal finnex
i use RC for the salt mix thinking of changing to seachem reef salt

Well, I would just check magnesium and work from there. I suspect that any magnesium supplement would be fine. The third part might help a bit, but it's really intended for tanks that don't get many water changes.
