How often do you do water changes? And what amount of water? What kind of salt do you use?

What does "s.22 .23" mean? If it's supposed to mean your Specific Gravity (SG) is 1.022 - 1.023, try bumping it up to natural seawater levels which is 1.026. The increase in salinity will also increase your calcium. You don't have anything listed that would be a major consumer of calcium.
Also, what brand test kit are you using?

 

[rickgidd]

api test kit, kent reef salt, salinity 1,022 to1,023 red sea magnesium test kit

 

[rickgidd]

15% every other week in the water changes

That halmedia(sp) algae is probably what's eating up your calcium. They need it to thrive and grow. You may have to start doing either larger or more frequent water changes, change your brand of salt to one with a higher calcium level, or start supplementing calcium.

Or get rid of the halimeda. Most people don't keep it for this reason.

well it came on some aqua cultured rock I picked up so will have to see how it goes if I can bump some additives I will try to keep it for now thanks
