@prsnlty said, I would wait until red slime remover is out of your system before dosing Fluco. Since you already have bryopsis, waiting few days won't have that big of an effect other then making the tank look little uglier. Fluco is very effective. However, for me, it took 3 weeks to completely remove bryopsis. You have to let it run it's course. Don't plan on doing any water changes during this time. I wouldn't even try manual removal. Once the algae turns white it will eventually disappear. If you can, I'd say run some filter floss in your sump to catch the dead algae. My filter floss had to be replaced every other day since the dead algae was clogging up the floss. Best of luck.
