Any great ideas on how to get rid of t his stuff that is on rocks that have things I don't want to get rid of? It is taking over sections of my tank... it's so much worse than GSP.
Make this device out of 1/4" stainless steel straw sealed inside a 1/2" hose with rubber band. Create a suction and scrape with the straw and suck up at the same time, into a filter sock inside your sump or a bucket. Works great.
