Magnesium controls the balance of alk and calcium. It's the addition of things like alk can cause calcium to precipitate out.

You need a two (or 3) part additive. Kalkwasser isn't the correct choice for this issue. How big is your tank? Bulk Reef Supply sells cheap additives and even dosing pumps if need be. If your tank is a nano you could just use the B-ionic from ESV.

So if I added kalk to my auto top off system would that then cause thee calcium to precipitate out because the alkalinity is already at its ideal levels?

It's only 34 gallons.

That link has a lot of good info. That being said. Try not to overdo it with dosing. How often do you do water changes and how much do you change?

Honestly I'd do 25% water changes weekly to get your calcium back up instead of trying to dose.

Okay I will try that. I just read that article. What I got from that is in my situation if I were to use an additive of calcium and alkalinity to raise it to 420 ppm it wouldn't precipitate out of the water. I could then have good stable water parameters. The only thing low would be the magnesium. As the calcium and alkalinity are raised though, they will be depleted quickly, and magnesium may not be needed in such a small tank where the calcium will just be taken up before it is precipitated. If it happens to precipitate though, I could just add a magnesium supplementation. I had talked to someone at my LFS and they said I should dose this Reef Code A by Brightwell Aquatics. It is a balanced calcium and alkalinity for reef tanks. Should I first start doing the water changes weekly and see what that does? Then try this? Only thing is this says to use this only with 1300ppm of magnesium. But from this article, if I added this since my levels are so low, they wont begin to precipitate out. Right?

Yes I would do water changes first instead of dosing. even if you dose your calcium might precipitate onto your heaters or power heard before the coral can consume it.
