Should I dose, should I do water changes?

Alk - 8.0
Calcium - 494
Magnesium - 1160
Phosphate - 0
Nitrate - 0

I will be dosing the magnesium by hand but just purchased BRS dosers for their two part. It seems like my Alk and Calcium are fine, even calcium seems too high from just doing water changes. Should I dose? And should I reduce the number of water changes or amount of the water changes because phosphates and nitrates are at 0 when I’m scheduled to do a water change. Tank is fairly new 7-8months. Have a slight algae issue.

Usually about a 10% water change per week is what's needed to keep your trace elements in line, personally I would try to get the magnesium closer to 1400 and just keep an eye on alkalinity and calcium before you start dosing anything else

The magnesium and calcium reflect what is in your salt mix. I can’t say if your values are accurate or not,
