Yep. For me on a reef tank my first priority is reliability/repairability. Reliable is stable and stable is king. If I can build it myself I can replace/repair it if it goes wrong.Anyway...longevity and equipment failure issues associated with high-end equipment are often completely ignored in discussions like these about why one might choose the basic and DIY vs. going all out on fancy things.
I have korallia powerheads that are 15+ years old and still working. Only things I have had to replace is the impeller shafts as I find they break easy (I'm heavy handed).
I have grown and propergated softies and lps in a tank with no sump and compact florescent lighting. Light, powerheads, heater and a ready supply of RO/DI, decent salt and test kits was all I needed.
A lot of SPS do need more as they are so much more fragile but I don't think a reef tank is defined by how many SPS you have anyway. I much prefer my mushrooms, zoas, palys, hammer and torch corals anyway.
Edit: it's a bit like freshwater lowtech vs high tech planted tanks. Similar results, different methods. The key to success with either method is knowledge.
