I used Kalkwasser for many years before switching to dosers. If you want to keep it really simple you can mix kalk into your top off water (presuming you have an auto top off...which is definitely a good idea for stability).
My recommendation would be to skip that phase and go with 2-part that you add daily.
You need: Calcium test kit, Alkalinity test kit, Calcium Chloride, Sodium Bicarbonate, Magnesium, some decent salt (I use Reefcrystals), and a refractometer (hydrometers are not very accurate).
Then you need lots of flow, some MH lighting, and a good skimmer.
It really isn't rocket science. You test you levels, get the CA up around 420 and the Alk up around 9.6dkh and you experiment with how much of each of the two mixes to add until you know what needs to be added every day. Once you get sick of dosing every day you can buy a doser. The Mag I would just "glug" in once a week.
There is no "right" way to do it, but the above is simple and effective. I suggest finding MH bulbs that are appropriate for your tank and have good PAR readings. There are plenty of crap bulbs out there with great marketing behind them.
If you describe your tank a little more I'm sure you will get some more advice as to equipment that would be suitable.
One word of advice is "patience." You will be infinitely better off by purchasing frags from a local hobbyist that is diligent about treating for pests. Let them grow and be amazed with how much better your tank looks in the long run. Don't buy maricultured/commercially aquacultured/etc. until you have a good handle on things.
Hope that helps,
