I believe I found the problem...

My calcium levels are really low. What can I do to raise them?

Weekly PWC with a good brand of salt like Reef Crystals should keep your cal levels around 400+. Short of that, you can use something like B-Ionics two part alk/cal solution to bring your levels up.

Or, make your own 2-part solution:
A Homemade Two-Part Calcium and Alkalinity Additive System (Randy's Two Part Formula)

I would try the frequent PWC`s first. Oceanic has a high calcium level.

Also moving this to the General SW reef aquaria forum.

Thanks for the replies. I am going to do the two-part solution. My attempts of PWC have only brought up my calcium levels about 20.

I'd seriously suspect your calcium test kit is flawed. 20????

need more info how long has the tank been setup. what do you have for your filteration system. do you have a large amount of acro corals in your tank, or mostly soft, have you been adding calcium and its not coming up. if so what product are you using?

hope i can help

A pwc should replenish calcium just about to 400 or more. How much water do you change and how often. How old is test kit? Dont add anything yet. Is this in your 37g? A 25% water change would bring calcium back to 400 or more.
