At least someone got mean. Since 1998 it's been all white glove treatment for bryopsis, we need a new concerted effort and as long as it involves damage to the plant in some way I'm down.
Being able to generate the entire outcome on a single test rock, before the whole tank is attacked including the non bryopsis portions is why our removal method is best. By not treating the water, and by scraping the bryopsis off rocks first then treating the barren spots with peroxide, we literally emerge with a tank free of bryopsis. Anything shy of that is snooze fest bryopsis work heh web posters always so judgemental. I see anything that burns the whole tank, the clean up crew, the corals, the ionic balances in the tank all for an approach that might work, and will tell within a few days, as fully inferior method but it's the least work requiring and as such it will remain more popular. The water dosing Kent tech m method works on enough tanks (my estimate 60% of bry tanks can be helped by mg spiking the water) it will always be the go-to method. But that rasp, it's a one time hammer fix with a full clean outcome.
