All I use is Kent products.....well most of them. Mainly for a reef I use Coraccel,Phytoplex and trace elements..once in a while some Strontium, and Liquid Calcium, and Tech-M,Iron,and Iodine...but you must be careful not to overdose and always follow directions..and always test for anything you dose..testing is very important to avoid future problems. once your all set and running after water changes and mixing salt with the trace elements in it you shouldn't have to dose.
