So today is the first day I tried using the refugium section of my sump. I'm using a 20 gallon high tank that I siliconed glass baffles. The refugium section is about 4 gallons. As seen in the video, I placed a 1oz ball of chaeto I got from Algea Barn. The Chaeto is tumbling, but some pieces are breaking apart and flowing into different section of the pump. What i'm concerned about its starting to clog up my return pump. Am I doing something wrong? Or what can i do to keep the Chaeto from going all over the place? Any advice is greatly appreciated.
