The diameter of the dish is about 7.5inches. Amount wise, i would think it is sufficient for a few spawn of fries per day. Really depend how much you pour in the bbs eggs.
Anyway here's what the website quote..'With a premeasured charge of about 0.4 grams of dry cysts, the Hatchery Dish yielded over 100,000 baby brine shrimp.'
But if you are hatching alot everyday, would recommend to change the water everyday.. (i use less than 3 mins to change the water and add BBS eggs. haha. Can PM me if anyone is interested to know how i do it..)
