I had the pleasure of visiting Birch Aquarium for work purposes (haha, completely unrelated to the hobby but still the best day of work ever) and wondered if anyone knew if their reef tanks received special treatment aside from obviously better lighting (elevated alkalinity/calcium/magnesium & nutrient control that we in the hobby employ), or if they just continually pump in natural sea water, as they do for their other displays? (Reefers in San Diego are familiar with "Scripps water". There used to be a spigot tied into the aquarium's sand filters that we'd use to get free nsw for water changes.
