This is going to be a very Newby type question, I have been in Saltwater for a little while but this is my first experiance with a protein skimmer. I have a 75 Gallon Mixed Reef with a 20L Sump. I installed a brand new Eshopps PSK-100 In-sump yesterday and I just want to make sure that I am doing everything right. The instructions say that the sump needs to be in 9-12" of water......I have it at about 10" of water. What I am getting right now is acting like a reservoire of water about 1-2" off the waterline of the sump. It seems like the pump brings in water and then pushes it right now. I did some researching on break-in periods and I just want to make sure that this is what the break in period consists of because of the oils from the manufacturer or did I do something wrong?
