Now with super foaming action!...
Makes your protein slimmer completely in usable, so you better have other nutrient control measures in place. Luckily my refugium is up to the task of serving as sole filtration.I did a half dose once, left the skimmer off for six hours like they recommend. And when I turned it back on it instantly foamed over. I figured ok give it 24hrs, no change, 48, 72, still no change instant foam. But my refugium is doing great keeping everything in check so I let it go for over a week, still foam crazy. So I do a 20% water change, still foams over. It took 2, 50% water changes so I could use my slimmer again.The fish do look pretty nice and happy so it wasn’t a complete waste, just wish they were more upfront about what it was going to do to my system.
