i guess i think this way because for the first six months that i had a s/w aquarium i didn't know anything except for the book (saltwater for dummies), and garf, i had never even heard of maast or reefcentral because alamo aquatics and texas tropical never mentioned it to me. i was at another chain store looking for something they didnt have so he called fin-addict, gave me directions and that where i first heard about maast.
