What ever is on sale.... Last purchase was 3 buckets of Reef Crystals $98 delivered (Dr fosters and smith). I also use IO by the 200g box. They run the same price as the buckets normally

If you are going to use IO prepare to dose calcium and other supplements to get multiple levels in check. In the latest study they have also shown that for whatever reason IO has issues with cyno = red slime algae. I would personally atleast go with something like Reef Crystals if you are going to keep a reef because it is more reef oriented in its makeup. I personally use Red Sea Coral Pro and have used Tropic Marin Pro Reef, both with good results, but i did switch to Red Sea Coral Pro because of the levels of phosphate in TM.
