Necessary additives

[yellowbellied]

I've not had any success with keeping brains or frog spawns. My tank is mostly FOWLER, but I just want one or two in my tank. Should I add strontium, magnesium, and the like to the tank? Do I need to?

For LPS you really don't need to add too much. The only thing I supplement is dripping kalk. Otherwise regular water changes will replenish most of the elements back into the tank. HTH
