can someone help i.d. and explain to me how to get rid of a fuzz like thing that is all over floating in my tank,i have tried many solutions frrom "algaefix" to hardening the water to doing massive w.c. and it won't leave the tank. it adheres to the rocks,the gravel and if stirred up will get sucked onto the intake of the filters on the tank. i have attached some pics maybe you can figure out from them.:help:
