The attached picture shows my current 20-gallon sump that supports a 100-gallon display tank. I think my DT consider low bioload: four different tangs (yello, blue, powder brown, and kole tangs all about 2-3 inches), 4 clownfishes ( less than 1.5 inch), one flame angel (1.5 inch), two gobies. LPS and soft coral only.
I use the first chamber as fluidized filtration, 2nd chamber has a too-small protein skimmer (tunze 9004) and a lot rocks in both DT and 2nd chamber. Recently I made a algae reactor just for fun.
It has been ok: soft coral grows like weeds, LPS grows steadily, too although I seem not able to maintain SPS long term, used to have some acropora and bird nest but got STN twice last year and I gave up sps for now . However, I always feel the fluidized filtration takes up too much space from my too-small sump, that I thought was a mistake in the first place. So I started planning to change how to use my sump recently. My original plan was:

So I started planning to change how to use my sump recently. My original plan was:
- remove the fluidized filtration gradually to free up the space eventually.
- with the space in 1st, I can get a larger protein skimmer, and possible run other reactors or other equipment later.
- then, for the 2nd chamber, upgrade the sump lighting to grow as many macroalgae as possible.
- my fluidized filtrations probably is doing better than I thought, do you think so? or, do you think this is just temporarily because I remove too much at once?
- And the most important question to answer is, given the small sump (and the above question), is my original plan worth it in terms of filtration/maintenance efficiency?
