I'm completely sick of dosing kalk. I don't have the means to hook my RO system to the tank, so a kalk mixer is out of the question
i've ordered some calcium chloride, and i'm going to try two part dosing. my calcium's slowly worked it's way down to 320ppm, even though i'm dosing 6 tps of kalk every night like clockwork. it's getting expensive, too, buying kalk from the LFS.
the two part system will give me more control to balance out my kH and calcium, and if it works, i'll look into some dosing pumps to do it for me.
I'll have about 9 lbs of calcium chloride in about a week, ordered from littlesilvermax, and we'll see how it all goes
I'm gonna have fun baking baking soda (sorry, geeky word pun there lol)
