whats your CA/KH dosing and testing schedule?

umm, once a month??? LOL. I never seem to have time to measure and all that stuff. I don;t have much in my tank yet either. But thats changeing, I better get a handle on this dosing...

I test every 2 weeks, just before a water change. I use RHF recipe: 80ml Ca, 60ml Alk, 50ml Mg per day via dosing pump.

I test before every water change (Ca, Mg, alk). I dose the water change to 440 ppm Ca, and 1320 ppm Mg, using IO salt (which tends to mix up with relatively high alk, mine is generally 11). I dose Tailored Aquatics products (Calcium Plus, Reef Magnesium) for Ca and Mg, and use a tiny bit of Arm and Hammer baking soda (to keep alk up) in between water changes. Since I do a water change every week (though I have occasionally gone 2) and I know how much my tank uses in a day, I directly dose the tank once daily for Ca and Mg (I dose a lot less Mg, unless I forget completely I just remembered I didn't dose yesterday). The baking soda I use once a week, in between water changes. Seems to work for me so far, but I don't have any SPS, just coralline and an open brain. I may have to try something different when I get some SPS in there.

looks like alot of reefers are using, the RHF method for keepin parms in line.

This question has provided some interesting replies! Good one.

I run a Kalk reactor during night hours only, and run a Ca reactor continuously. Both are controlled with pH meters and peristaltic pumps linked to the controller. These supply all my Ca/KH requirements.

I test Alk once per week (unless I'm having some problems). Maybe test Ca monthly, but I generally assume it is linked to Alk. I might test Mg only every 3 months. I've never had to dose Mg, which I cannot explain.

yeah this applies to me as well, i use reefers best salt, so maybe thats why..?

Doesn't explain it for me...I've used a variety of salts. Weekly 10% water changes, possibly?
