not judgeing you or anything, i have just been there and alot of times i slip into impatience.
TRY, try, try to take it slow. get the stuff you need before you get the stuff you want.
i was buying coral before i had a refractometer and i was using a hydrometer. what a mistake..... my hydrometer reads 1.026 and the CALIBRATED refractometer reads 1.021!!!!!
