Actually, the algae scrubber is a completely different topic. They are catching on, but have yet to become mainstream in the hobby. As you have probably noticed, there is a long running thread on algae scrubber systems here on the forum. Outside of that thread, you will not find any regular on this site that uses algae scrubbers. In my experience, the same will apply for other internet sites you visit. I have no experience with algae scrubbers, but can say that the large majority of hobbyists in the United States do not use them.
The large majority of successful marine hobbyists use a sand bed, live rock, and a protein skimmer as their only filtration. The UV Sterilizer is an accepted addition, and one that I personally strongly support. However, again, you will find that only 10-20% of people you talk to have a UV on their systems. I personally would never consider a marine aquarium without one, and consider it "insurance" against disease.
