guess im the outcast here but i do 10% monthly on both my tanks
i was a weekly person until i realized my tank looked better and is healthier with small monthly changes instead.
been working for awhile now, if i see its not working then ill go back to the weekly changes
i dose weekly with calc, alk and iodide, run carbon and phosban
