If you trust your source than why question them. On the other hand if you don't like what they do or trust a certain vendor or source just don't buy from them,it's as simple as that(business is business)when you go buy a car do you ask the dealer if the screws used to put the car together where made in china or if the glass was made at a certain temperture(NOOOOO)you go on the reputation of the car company. When you buy sneakers do you ask if the strings are 100% cotton(NOOOO).You buy them by the BRAND there is nothing in this world not sold by brand. ALL GLASS,OCEANIC,FLUVAL etc all brands. we may not want to believe it but the world runs on brands,The fish we buy may not be a "brand"but we do buy from who we feel is reliable and trustworthy ,therefore the vendor's we deal with are brands plain and simple(fish farm,tuic,wish list etc are all brands)they advertise like any other company and build their reputation like any other company. Thats the bottom line we all live or lives by brands(hell the computer you are arguing this point on is a brand,unless you have a no name computer)All these high and mighty so called no it alls need to get over themselves,no company ,business,brand etc is going to tell you evry thing you want to know,they may answer a few question. But in the end it's business plain and simple.
