Linda, when I had a nano reef I used a diastolic feeding pump to automatically add water to compensate for evaporation. I think it came out to a couple hundred mL/day. I got the pump off eBay for about $100. Well worth it. What's another $100 for a reef tank? ;) Unfortunately it's a bit noisy but it did save me a lot of work in keeping the water level constant. - Matt On Fri, Jul 24, 2009 at 2:23 PM, Linda Knapp <linda@bozuk.org> wrote: > I had a lot of problems keeping my saltwater nano tanks cool enough. > One problem is the high wattage lights.
