I ask: "Gotta lot of extra money and time on your hands?" If they are still interested you may have a future reefer. Usually they run for the hills.

haha for a laugh next time i may just say its simple really couple shots of water, cup of table salt, find an old desk lamp somewhere,throw in some pricklys or an ol trout and presto instant saltwtaer aquarium.yup thats how i started mine;)

For those people I don't want to get into it with....my answer is "SALT" :lol:

when they ask i try and sell them my set-up.:lol:
