mixed 2-part storage

I think he's saying he goes through a jug of mix every 20 days, at least that's what I got from his post.

Even with good quality chemicals there is a bit of sediment in the bottom of the Ca mix. Not sure I would want that going in my tank, so never mix it in. When I switch jugs I carefully pour the left over into the new jug without the sediment.

takes me about a year to go through a 1g jug of alk and calc. i dont mix and theres never any sediment in any of them

I mix 200ml of Ca and Alk into 4L milk jugs, and yes, there is a slight bit of sediment on the bottom at the end. That's why I shake it a couple times near the bottom. I use Seachem Reef Buffer and Reef Advantage Calcium.

Even the best calcium chloride is going to have some impurities in it. Perhaps a medical grade would have a minimal amount, but that would be going way overboard IMO. I don't know what the sediment is in the bottom, it could be anything, but it definitely isn't calcium chloride.

The Seachem Reef Advantage Calcium has other stuff in it, incl Mg and Sr, which maybe doesn't hold in mix as well. Just want to stress though, that the sediment/residue is very small, just enough that the last bit of liquid is not totally clear. And certainly not enough to be concerned about.

What I do like about this product, is that I never have to add Mg on its own. I test occasionally and it stays around 1400 - 1500, which is even on the high side.

Oh ok I totally didn't interpret it that way but reading again I would have to agree with you my bad
