The way the numbers go - and I hope everyone agrees - it doesn't matter specifically what your numbers as long as you stay consistant on your trace elements and spgravity, and I mean constant, you will see the other numbers fall into place as the system matures. When you get a comment like mag needs to be 1300, all that really means is its worked for him, therefore shoot arround there and keep it constant, nothing likes numbers bouncing everywhere.
Ph should resolve itself with your core numbers 0 and trace elements constant either through a dose chemical or water change is the bottom line. Every single one of the good tanks on this site have researched extensively, and I know cause we've talked, I recommend a visit to a library in your future.
