Thanks Organism.
My sand is not flying, and the flow is pretty random.
As for bulbs, I do have another question: ATI isn't easily available in Canada, from what I can find, although I could be mistaken. But I can easily get Giesemann and UVL. Giesemann is about $6 more each. I dont mind spending that little bit of extra on the bulbs, unless there is little difference. Did you find that the Giesemann were that much better to be worth the extra 12 bucks?
