How does the HOG.5 compare to the SM100? I currently have a DIY SM100 on a 90g tank. It has a light feeding schedule, 7 fish under 2" long, some corals and some anemones. I'm interested in switching for several reasons. The low energy cos. Hopefully it's more quiet, the plumbing on my scrubber is loud. I'm in Canada and ordering the proper bulbs costs a LOT of money.
Would one HOG.5 keep up? Would two?
