currently I have pretty good param's and I haven't done much with my 14 biocube. I removed the bioballs and blue sponge so far. I added liverock rubble in chamber 2( I want to make it into a fuge with some chaeto, but can't find a submersible light). In chamber 1 I left the filter in for the past couple weeks to add in cycling and removing crap that came off the rocks, there was a ton of it btw. I will remove the filter cartridge as soon as I start adding fish, but till then I've been rinsing it out weekly. My tank has fully cycled and it took a little over a week.
I seriously considered going with the nc12 skimmer but decided against it. I think a fuge in the 2nd with chaeto would do a much better job, considering you kept up on your water changes.
