Feed Seachem metroplex bound with Seachem focus with their food. It may take anywhere from 7-21 days to work. I recommend feeding this once daily until you haven't noticed white poop for AT LEAST 5 consecutive days.
You can use 1 level measure of each med with 1/2 tbsp pellets or 1/2 tbsp of frozen. I prefer pellets because I can freeze them to make the mixture last longer. Also, I rarely use pellets other than as a "treat" so, even with the medication in there, all of my fish have devoured the mixture. You can use a drop or so of garlic to make it more palatable. Also add a smidge of tank water to help disolve and mix the meds
This IS regarded as reef safe. You can also, if you don't already, run carbon while doing this to pull any leached meds out of the water.
