I did my whole tank a couple months ago. Didnt encounter any ill effects on fish or coral. If you look through my build thread i think i documented it in there on how much i added and stuff. Cant remember at the moment.
I've never dosed an entire system myself, but when I need to administer PraziPro, (If I've got a sick fish, or introduce a new fish), I always gut load brine shrimp to get the meds in the fish.
Get a helping or two of brine shrimp, and put a few drops into the bag with the brine. Let it sit for a couple hours and then feed the tank.
The brine shrimp will survive for a few days in the fridge in the solution, and when fed to the tank, the fish will devour them.
How much do you dose into the bag of brine shrimp? Depending on the amount of water or do you just throw in a capful?
I put enough in the bag that the water becomes cloudy/hazy. I can still see through the bag and see the shrimp swimming around
mrx, what do you mean "open it up"? I have the cup as high as it can go. ..is that what you mean?
