Does everyone let algae grown on the marine pure plates or do you scrape/sponge it off? I am assuming to keep the 'pores' open I need to get it off...

Excellent. Thank you. I will go awhile and see what happens...I let it grow on mine. It got long and wavy then started to break off and float away. It got caught up in my baffle sponge and I tossed it out. As of now, it's clear with some coraline algae growing on it in places. I do have a few hermits and snails down in my sump so maybe then cleaned it off over time.
