Saltwater fish tanks

Here's my two current tanks, a 46 gal. reef and a 75 gal. reef. The 75 has a refugium under the stand, while the 46 just uses an external filter. Both are beautiful to look at, although the 46 is battling an algae outbreak these days. If you haven't done marine tanks before, they're not cheap to set up or maintain. Figure about $30 per gallon to set up a basic tank. I spend about 15 minutes each day doing basic maintenance/inspection, and an hour or so one day a weekend doing water changes. The 75 reef is lit with four 130 watt compact fluorescent bulbs, and the 46 is lit with an LED canopy that I built using CREE XRE LEDs.
