Hi all,
i will be trying Randy's improved 2 part dosing method, however where i live( London, UK) some of the products are not available. We do have though a great supplier of pharma grade chemicals. I need your advice if i can substitute Randy's with those:
For Magnesium he suggests Epsom salt and magnesium chloride hexahydrate. What is actually Epsom salt- is it Magnesium Sulphate Heptahydrate? Cause those 2 products are available to order and i get hold of them.
What is the best ratio to mix those 2 Mg solutions and do i mix them together?
For calcium, can i use:
calcium chloride only, as they dont sell calcium chloride dihydrate. This one:
And for alkalinity, can i use this one:
Thanks a lot. Ross
