I have a refugium below my DT tank using felexible tubing for the water transfer. I am getting alot of algea build up. Any ideas what I can use to move the water from the tank to the refugium? unfortunatly, DT is near a window with a shade, still getting algea build up. Afraid it is a breeding ground for parasites. Is tubing from the hardware store safe? Maybe I could use black tube, will that help the buildup?
