No I'm not dosing cal. But Im dosing alk.

SG, asking what is your salinity?
How are you dosing Alk? What product and method?
Also what is your Alk?
I can't think of a reason Ca+ would rise unless Alk was also incorrect/or dosing!

You have to know salinity of your tank water (how much salt in it). If you have a refractometer, you can read specific gravity (SG) of aquarium water. Refractometer scale is between 1.000-1.030 and desired value is like 1.024-1.026

My salinity is 1.025
I'm use BRS 2 part. I have a dosing pump. But I'm have not start use it. So I'm dosing manually. I'm a busy person so I don't have that much time with tank. Alk are 7.4 right now. I know is too low. I will try to have some time to setup the dosing pump. But the problem right now is the cal keeping going up... I only have some sps but most of them is not doing good. -_-!! Most lps are doing good.

What's your tank size, I had a similar problem and what I did was two water changes one one week then the following week of 15%. The other thing after checking my alk and cal I only dose my alk to bring it up to 8.2 - 8.4 this should start to bring down your cal. If your running gfo, turn it off the acid will keep bring your alk down. Go to marine depot website and use there reef calculator to gauge how much to dose to bring up your alk. I suggest dosing fractions at a time so you won't shock or kill you corals. However the easiest way is probably just 3 to 4 weeks of water changes no dosing
Hey, its impossible for calcium to raise unless you dosing a calcium product, or using a calcium reactor.
Second option is your replacing evaporated water with salt water. You must replace evaporated water with purified water, not salt water.
Third option is its a test kit error. Calcium test kits can be done wrong by you, and they are not very accurate.
Id suggest taking a sample of tank water to a fish store and have them test it.

Unless you are topping off with tap water or adding calcium without knowing it, I'd lean toward testing error. As noted, calcium does not rise on its own. A lot of folks have issues with the Hanna calcium checker.
That said, 600 ppm is not harming corals even if real.
Alkalinity at 7.3 dKH is fine.
