Been planning out the uses for the back chambers and could use some input. Most of you are probably familiar with the nuvo 20 chamber layout, but I've attached an illustration to this post just in case. The diagram shows where I plan to put everything. Only thing is, I realize the overflow chamber (D) as well as the media basket, are so small that putting chaeto in it would not provide as much impact. Intank has a refugium basket that would fit in the secondary chamber (C) and would give more room for chaeto and rubble. The problem then would be that I have no room for my reactor. So the question is... is my initial plan sufficient? Or should I put a refugium basket in (C) instead? If so, should I return the reactor?
