Hello.
In the middle segment of my sump I have a chamber of bioballs I want to be rid of soon. I'd like to replace the bioballs with either:
1. A second protein skimmer under $400. I already have a Aqua C 180. It does a pretty good job. I don't know what kind of skimmer to get. I have a 125 mixed reef.
Or...
2. A Korallin biodinitrator I read about them with the sulfur-based media. Sounds interesting. I wonder if it really works.
I am looking for advice. I appreciate input from anyone.
Matt
