How are you guys removing pink encrusting coraline algae that is growing at the gravel line in deep (30") acrylic aquariums? - (without leaving scratch marks). I'm currently using the Continuum pro scrapers (24" & 34") but it's not working. I also use a mag-float large & extra large with an easy blade glued on and a modified continuum blade which is worthless against this stuff! This stuff is like concrete and my arm is just not long enough!
