I went with a 12" by 30 bashsea twisted with a 3500 gph pump and an air injector pump...
Im going to try and piece out what youve explained there lol... its late and Im slow
The skimmer will be getting water right out of the first chamber where the tank initally drains into and the reactors will take water from where the skimmer will dump back to the sump.
Thats the way i figured it should go anyways???
