Is the aroma as strong a scented candle or air freshener?

It depends on the size of your diffuser and the square footage of your space. Mist is gaseous and will expand to fill the space, so if you would like a stronger scent, use the diffuser in a smaller space (and vice versa) or add a little more drops of essential oils.

Where do I place the oil if there is no tray above the water?

You place 3 - 5 drops of essential oil into the water reservoir directly. Diffusers are designed to mist essential-oil infused water, which is different from heat-based diffusers that evaporate essential oils over an open flame. ZAQ diffusers are a safe alternative to heat-based diffusers.
