Magnesium high.

What is high PPM??
What are you using for salt mix?
And what test kit?
Magnesium is really hard to raise and virtually has no effects on marine life even when it's really high.

I'm thinking that is 1500 ppm.
And that's fine. I maintained a tank for years with 1500 ppm Mg.
As a matter of fact lots of folks with nuisance Bryopsis algae will raise the Mg. to 1500 ppm+ to battle it.
So you're fine with it at that level.

You may want to go through the test and make sure you do it step by step.
I.O. salt mix is usually quite low in MG. and almost always needs some buffering.
I use the I.O. reef crystals and it's more in line with natural reef water conditions.
Would this be the Red Sea Pro kit with alk,Mg and Cal?

What is your salinity at? And your calcium? As already mentioned, 1,500 ppm is really not that high anyways. Much better than being too low!

I would not worry about it. I had an irritating Bryopsis problem in one of my tanks and decided to finally hit it with Kent Tech-M. I had not tested Magnesium for a couple years and found it was 1200. All of my corals, including SPS were fine. I raised the level to over 1800 and the corals had virtually no reaction. Even pouring the concentrate directly over Acropora corals had zero effect on PE. The Bryopsis was gone in 3 days and the only effect I could notice it that a few zoanthids got a bit pale but are still healthy looking. I am sure color will return eventually.
That calcium level is just fine.
If your tank is not that big and the bio-load is small you should be fine just changing water and not dosing anything.
Just remember that most failures happen cause new folks will dose too much to control things they don't need to.
The numbers don't need to be perfect for success. They just need to be in the ball park and steady.

You are all set then. Magnesium should be roughly 3X as high as calcium, so you are right where you need to be! Although with those numbers, I suspect your salinity may be a little higher then 1.025. But either way, I would not change a thing.

You have a hydrometer. I suggest you have buy a refractometer along with a bottle of 35PPT calibration solution. Get an auto temp correcting (ATC) refractometer. You should be able to get one for about $50 online. Use the calibration fluid every time you check salinity.
I am betting your salinity is actually 1.027-1.028.
Having used I o for a while before, I suspect measurement error as I o is normally very low in mag
