I was wondering what other people though about GARF's approach to reefing. Has anyone tried the techniques they promote - Agrocrete, low tech lighting, Grunge, low tech skimming, seeding coralline, etc. ? It just seems that their methods are much cheaper and simpler than what you usually see, and yet they claim great successes with it. I cant figure out if they are primarily commerical or primarily research oriented. They also seem to promote Seachem products heavily and I was wondering if it was genuine satisfaction or just underhanded advertisement. Any thoughts?
