I wanted to keep a fuge for pods
but then I was reading and found out this is a terrible Idea. Pods
need high nutrient water to flourish and corals like low nutrient water so if you want pods
you should create them in an entirely different system. also its just another place that you have to maintain and clean. I use my area of the sump that is meant for a fuge for a settling area. its bare bottom just like my main tank but with low flow this way a majority of my detritus will settle in this area and ill be able to easily siphon it out.
Extremely Informative link will take some reading time however...Current Discussion: Refugiums - The Reef Tank
Now, I'll admit that I did not read all 15 pages of that thread, but I have to say that I've never seen anyone claim refugiums cause high nutrients. Not once.
I can also say that since I have added mine, my Nitrates and Phosphates have dropped to have what they were (and they were pretty low to begin with) and are both rapidly approaching zero.
I have also seen an explosion of copepods and amphipods both in the fuge and in the DT. More than double in a couple weeks.
don't need high nutrient water, they just need food, be it in the form of phytoplankton, or detritus from fish food and waste. I spent weeks researching the refugium concept and never heard anyone say they cause high nutrients or are no good for pods
