thanks in advance

Just let the corals lower it. Dont dose either one till you get to where you want.

water changes.

water changes.

D&D H2ocean comes with a very high cal and mag so water changes wont help. I used the same salt before I switched to RC. Your corals will consume it and eventually water changes will not be enough for your cal and mag replacement. I personally, would skip a water change.

+1

also stop dosing the calcium side until it gets to were you want

raising KH will also drop MG (a little bit). Water changes will always be good it will balance the values.

I think you are fine with the values where they are ie/ no worries
As other's have said, time will lower them as your corals grow start to uptake them more.
What size tank do you have? Can it handle to miss a water change until you get your perimeters were you want them?

I started this hobby using h2ocean and it took me over a year to get the calcium down to 420. Plus I had a lot of coral. The fresh salt mix has a calcium of about 600 from what I remember. More frequent water changes will only raise it

my tank is 4x2x2 ft and the total volume is 564l including the sump

thats exactly what I have, it will take a while to balance it all out, I hate to say this but if you want to drop them faster just get more coral

i have been adding Seachem reef builder around 3 teaspoon per day to see whether i can bring up the KH in the attempt in bringing down the Mg and Ca. i will miss water change .

3 teaspoons (1 tablespoon) will bring it up by .5 with your water volume. In my opinion, 7 dkh is a little low. bringing it up to 8 over 3-4 days will help a lot

i understand but i am using Zeovit here whereby the required DKH is 6.5 to 7

Oh, yea sorry I didnt know that, you forgot to mention that. So just maintain the alk at 7 and let everything else go down to where you want it
