Just tested mine and its 500ppm. According to my research ideal levels are 420-450. Am I ok?

500 is fine, do you have any sps?

Do you have a ton of SPS in your tank? 500 is a little high, if you dose anything just back off a bit and let it drop naturally.

Ive ran 600 for well over a year. No issues on sps dominant
