hi there.. where did u get your K2so4 in england?
i can find it but only not stated as k2so4 yours proberly is pretty pure..
it will matter how much you dose because your plants will use so much or so little.. and idealy you want to get the same PPM as any of the recommended PMDD products to keep the rule of dosing etc.. but again you can work on your own method.. im sure the actuall product is good enought for your tank.
have u got anymore specific info on the product.. any stats from the back of the pack?
glad you got it tho
i take it you know where to get everything else?
have u got CSM from the US? im still awaiting mine :S
i have mg, i know where to get kno3, and im waiting for the CSM, then all i need is phos now. which i think i have.. and of course the k2so4.
good luck mate, try mixing with to the chuck gadd formula, you 'should' get about the right. do u know the percent of k2so4....
