Proper water quality for corals

[Europa]

I have a few soft corals in my tank for about 2 weeks. They are doing well, but I measured the water and think the parameters are a little off.
Calcium 360 mg/L
Phosphate: 0.5 ppm
KH: 2 dKH
How should I start the adjustment?

It could be your tests are off.
How old is the tank?
How big is the tank?
What test kits?
What brand of salt are you using ?
What is the salinity of your tank?
How often do you do water changes and how much each time?

There is NO WAY your alk is 2

Thanks for the answer. Here are the parameters:
How old is the tank? About 6 months
How big is the tank? 60 gallon
What test kits? API
What brand of salt are you using ? I’m buying saltwater at my local store
What is the salinity of your tank? 35 ppm
How often do you do water changes and how much each time? Every week, normally 5 gallon, but 10 once a month.

Those test kits are not very easy to achieve accuracy

So what should I do?

If the corals look good, slowly invest in some additional test kits. I use a lot of Salifert products. I would recomend that one for KH for sure, it's the one I use. That number seems to be the most out-of-whack. But as long as things look good, keep doing what you're doing. It doesn't sound like you're trying to diagnose a problem so whatever you're doing is working.

When I first started reefing, I would bring water to my fish store to be tested. Never hurts to have a second set of eyes.

I actually re-tested KH and got 9. So I think that is good? Still concerned about calcium, but will teste at tomorrow.

Yes 9 is a good dkh

That is better! At a DKH of 2 you would be melting your sand and rocks.

Softies are not as critical to keep calcium high as you need for stonies or clams or some algae. Could be the test kit. That number is always a bit weird with chemical testing.
