I have a Red Sea Max 130 D set up that is 21 days old. Tank has been clear and water spotless. Did a 20% water change yesterday. Turned off pumps, skimmer, and Heater during change. I did NOT stir up any sand when filling the tank back up. I also cleaned the skimmer box out. Since then I have very tiny particles being recirculated through my pump. I am not sure how the skimmer should be set up. I have read just about every post and have tried everything. The problem is I am not sure what I am looking for and not sure how to adjust it if I did know what I am looking for. Do I have too much water? Foam? See video below. This is a 130D system with pumps & skimmer built into back of tank.
