40GallonReef Posted October 5, 2011 Share Posted October 5, 2011 So I am having a little trouble getting my calcium to rise. I have only 4 LPS corals in a 40 breeder. My calcium stays at a constant 400. I have been dosing calcium for about a week and it has not raised (i have been dosing 2.5 Ml a day). I thought it might be because I need to dose alkalinity so I bought a KH test kit and it is at 10. I have heard this might be because of a magnesium deficiency, is this true? I do not have a test for magnesium. Thanks in advance for the help. Link to comment Share on other sites More sharing options...
NoobtoSalt Posted October 5, 2011 Share Posted October 5, 2011 possibly your mag. What salt do you use? I have found that if you use the Kent Reef salt most parameters stay consistant. Link to comment Share on other sites More sharing options...

Smann Posted October 5, 2011 Share Posted October 5, 2011 If you dont have a high demand for calcium 400 isnt that bad, you do need to balance all three though, Cal, Alk and Mag but on a 40 water changes should take care of most of that Link to comment Share on other sites More sharing options...
Saltfinsax Posted October 5, 2011 Share Posted October 5, 2011 Yea 400 isn't bad at all. I would just stay with water changes. Link to comment Share on other sites More sharing options...

Bigjohnwoody Posted October 5, 2011 Share Posted October 5, 2011 I have been using red sea coral pro from the beginning and my mag stays at 1350 with weekly 10-15% water changes. I would just keep it at 400 and be happy. Anywhere between 380-450 is perfectly fine. Consistency is going to be your biggest friend. Link to comment Share on other sites More sharing options...
