Searched around a bit and I cant find the answer to my question... I want to add a refugium to my setup but am concerned about removing the bio balls from my wet dry.. Couldn't I just use a 10g tank, drill a bulkhead towards the top that will overflow into the return area of the wet dry. Use a minijet 606 to provide water to the refugium.. Would this setup be okay? So the refugium would be after the bioballs. I have a basic 10g tank in the basement that I would like to use but want to be sure that I am not going about it the wrong way. Thanks guys
