Maintaining Mag....

[pshea]

I am constanly adding mag to my tank, every night I add 9 tsp. The higest I have gottin it is 1200ppm, I know I can get it up to 1340ppm say but I am really getting sick of having to add everynight. I tested my salt mix and it came out to 960ppm, the only salts I have access to here is Instant Ocean and Coralife, I just switched to Coralife and my sps seem to be liking it better (thats good), but I switched because it was claimed this mix had 1247.5 ppm Mag, here is the link:

I was thinking of going with H2Ocean salt mix and was wondering if anyone here is using it?, or if anyone has any advise on maintaining a good mag level without having to order this supplement all the time....
