The strategy that works with me is high flow and lots of natural filtration and no mechanical filtration. This works great for me since my tank is very well established(9 years old). My tank is very well established as far as natural filtration goes with bacteria. I got rid of my protien skimmer about a year ago and I still have undetectable nitrate. Since I have done this I have seen even better growth in my corals. I believe this is because the increased nurtient levels make most of the corals I have grow faster. When I say nutrient levels I mean disolved organics, pods, etc. things that the protien skimmer takes out that are used by corals. I believe the nitrate has still been kept undetectable with no protien skimmer or any mechanical filtration is because of a very well established tank with ample nitrate-processing bacteria from good live rock and medium(~3 inch sand bed) that I stir up a little sometimes and also lots of xenia that is growing fast.
I personally don't like SPS. I like corals that move in the flow like xenia and soft corals and the brillant colors of zoos/palys and ricordea. I think LPS and soft corals make for a better looking and more interesting tank than SPS dominated. I think the whole craze with SPS is because its harder to keep so there it is seen as a challenge and therefore more prized than soft corals. I choose my corals based on how they look and I think soft corals make for a more impressive looking tank than SPS. People see xenia as a pest and Acropora as a prized coral but I see it the opposite. Acros looks boring to me, the hard skeleton structure that would come off to non-reefers as a fake coral. I would think to hear the infamous phrase by non-reefers "wow, is that real?" more from SPS than softies. I think people are much more impressed by the looks of leathers, pulsing xenia and the stunning colors of zoas, rics, star polyps and LPS like frogspawn.
Anyway here is my list of corals as of now:
1. green star polyps in several different places.
2. 4 types of zoas: radioactive green, eagle eyes, purple, pink, and yellow. also a couple brown/green palys
3. toadstool leather
4. green frogspawn
5. xenia: elongata and white
6. orange/blue ricordea
7. red bubble tip anemone
and more...
