I've read a whole lot on here, in books, and online, and I still have no idea... What are your thoughts on the following?
1) Lighting fixtures. I'm slowly setting up a 180g (72x24x24) reef tank, in which I'd like to grow corals, probably including some SPS eventually, but not necessarily a ton of it. My original plan, based on aquarium store recommendation, was to get something like the Coralife Aqualight Pro (3x150W MH, 4x96W PC, 4x1W Lunar) (see here). This seems roughly equivalent to a fixture by Orbit (here). Any recommendations as to brand?
More importantly, I'm wondering what my other realistic options are. a) those two fixtures above are propped up several inches above the top of the tank, and I'm wondering if it will be blinding to someone sitting on the couch viewing the aquarium. Moreover, I'm not a huge fan of the shimmering look, I could take it or leave it, might even prefer the non-shimmering look; what do you recommend in the non-metal halide area?
Any comments pros/cons would be very helpful since this is a large chunk of change I'll be throwing down.
2) Power Heads. I was going to go with 3 SEIO 500 gph for circulation, but they're a bit bulkier than I'd like (though most others I've seen are even bulkier). Are there any good quality power heads that leave less of a footprint? Any recommendations on cost/quality, too?
Anyone know anything about the quality of these Maxi Jet 600s? Hard to tell size just from a single picture on the web, even with the dimensions.
3) While I'm here, might as well ask for recs on an inexpensive but quality pump to use here and there, not in the tank itself, just whenever i want to take large amounts of water in and out or transfer from various buckets and such.
Thank you all...
