Mine has been running for about 10 months now. A minijet 404 pushes the water. It works fine. More flow would abuse the large pulsing xenia. Do remove the bio balls and sponges. Add a small bag of Purigen and carbon.
If I had it to do all over again, I'd seal off the lower return and make an overflow out of the upper return so you get some surface skimming action. Folks have done this and report excellent results. I've also seen a tiny skimmer stuffed inside the back with only a small portion of the collection cup showing.
I bought the factory stand a month ago. IMO it looks fine. It got the thing off of my desk!
Mine houses an
Orchid dottyback, hermit, 5 astrea snails, large chunk of LR with a couple rocks in front, a large growth of briareum, large pulsing xenia, some glass anemones, small polyps, shrooms,
peppermint shrimp, bubble algae, macro algae, and the occasional aptasia. It's pretty low-maintenance. It has 2-3" of sand. Nitrates read zero. Cool.
