whats the Best Alk cal mag supplementing for nano

[saltwater4life]

Hi I’m wondering what’s the best supplements to dose to keep my alk, cal and mag in check. I have a 20gal with about 20 corals ranging from a big acan colony to an acro frag. I was looking at BRS for straight alk mag and cal but would I benefit using something with other trace elements?
thanks
Currently
Mg 1245
Cal 410

I should of mentioned that I’ve been doing 25% water change. Sometimes all at once or sometimes broke up throughout the week. But now that I’m getting more frags and growth I’m noticing my levels are slowly falling behind.

Kalkwasser, then if your consumption is higher, then consider All for Reef with separate alk or ca doses to keep parms in the range you want to keep.
