Main reason I was leaning toward kalk is for the pH increase, but all reef looks promising too but without the pH boost. Have you used all for reef before?I replied this on someone else post.
From my Expirience using kalkwasser is that it’s very hard on pumps. Using it on a ato is also a problem because you don’t evaporate the same amount of water all the time.
So you have days that you dose more than other and there is no way to make sure you are dosing consistent amounts of kalkwasser.
For a frag tank I would rather you use a small single dosing pump. BRS dosing pump is cheap and effective. You can dose “all for reef” from tropic Marin it will dose all your needs for that tank with just one dosing pump.

Tropic Marin All-For-Reef is a revolutionary approach to dosing, combining calcium, alkalinity, and other trace elements into a single, easy to use solution. It's no longer necessary to maintain two, three, or four solutions, or a complicated reactor. All-For-Reef is a balanced source of calcium...www.bulkreefsupply.com
