Correcting Levels

[imclownfish]

Hi,
I noticed my corals were not doing as well as they once were so I checked the water parameters. I found that my magnesium, calcium and alkalinity levels were quite off. Magnesium was 1000ppm, calcium was 360ppm and alkalinity was 6dkh. What's the safest and fastest way to bring these levels back up to optimal range?
Thanks in advance

Well, are you using any supplement method now?

No, I was relying on water changes using instant ocean reef crystals.

OK, so then I'd go about picking a method for routine supplementation, and then you can decide how to correct values using what you have on hand.

For magnesium, look to a magnesium supplement, either commercial or DIY.

You're welcome.

After you pick what you might want to use long term, we can advise further on how to make the corrections.
