Ive got some questions for you guys about a skimmer i just got. Im new to the hobby so excuse me. I have a 65 gallon tall system that i just finish putting in water about an hour ago. Anyway i have a pro clear aquatic MPS75 skimmer. It doesnt seem like want to foam no matter what i do. It does have a valve that when i move it, it moves the water up and down in the skimmer but cant find anything else. It does bubble just dosent foam into the collection cup. Also like i said i just set up this tank so it is still cloudy and when do i need to add my bacteria packets to the water.
