Seachem products perplexing

[e46er]

I (along with most people) buy bulk chemicals because they do the same thing and are much much cheeper

for calcium i use dow flake which is calcium chloride
for alk i use baking soda which has been baked for an hour at 400 degrees in my doser for slight adjustments i just use reg baking soda without baking
and for Mg i use mag flake which is a combination of magnesium chloride epsom salts
