hello, i was going to get the following dry chems:
K2SO4 -potassium sulfate (i hear it can replace KNO3) - 2lb
KH2PO4 -mono potassium phosphate - 1lb
MGSO4 - magnesium sulfate - 1lb
and have it mixed 60-15-25 parts, with 1000 parts DI water...makes 15 liters of solution (and i would dose daily with 30ml (55 gallon tank), and would get 16 months out of it)
but i was told i have hard water, so should i skip the magnesium sulfate?
the reason i can't use KNO3 is because i am in canada, and can't import it safely.
i would be buying from here:
it would cost $33 ($8, $7, $3, $15 shipping)
i am wondering if the chemicals i chose, the mixture i chose, the dosage i chose and the site i chose would be good, or if there is something better for me to use.
also, where would be the best place for me to get CSM + B?
