I currently have a Octopus NW recirc 200 on my 90g "its rated for 300g." I am downsizing soon to a 60g. I have a coralife ss65 as well. Orginally I was gonna use the coralife skimmer. But I really would like to use my octopus skimmer. I am afraid it will over skim the water "take the trace elements and calcium out?" What do you think ?
