I want to dose only potassium for few days and as we know k2so4 can be used for this purpose. But i have noticed companies like seachem, pfertz do use soluble potash (k2o) as their potassium supplement. AS far as my knowledge is concerned k20 is derived from k2so4 only. So is it enough to dose k2so4?? i don't want that unnecessary sulphate in the water. or should i look for soluble potash for better result??
please enlighten me up.
