I have 5 tanks so I shop around local aquariums & online. Because I live in Sydney I order online from Tech Den. They are the most reliable online aquarium store by far. They have a wide range and the best prices. The delivery is always seamless & fast. It's the first place I go to when I need something. Only negative is wish I lived within a distance where I could shop for instore only items. But that in itself shows the reliability. If they're not confident they can deliver it, or deliver it in one piece, then they don't - and they tell you they don't. There's none of the pay and then find out later thing going on that happens with every other online outlet.
