I would return this tube and stay with the one you had. The "daylight" tubes are by far the best for plant growth, as they have a kelvin rating between 6000K and 7000K. Kelvin is the measurement of the colour temperature of light, and the mid-day sun is around 6000K. They are also more intense light (stronger) than the "aquarium" type, so you will have improvement on that score as well. Plus they provide a more natural colour rendition of fish and plants.
Leave the hood and glass; there should be glass between the tube/fixture and the water to avoid splashes (that could cause the hot tube to explode), rust of the fixture, and burnt fish if one should jump [many do].
