Doesn't sound like you are?
If you're going below 15ft use a red filter on the camera to replace the red spectrum of light, which falls off first underwater. If you lose one of the three primary colours your video becomes muted.
Above 15ft do not use a red filter or all your video will have a red look to it.
Professional housings have the lens shoot through a "bubble" to compensate for the curveture the water creates, also you usually use the widest lens possible and get the camera as close as possible to the subject.
Water is much denser than air so sharpness drops off fast underwater. You compensate for this by getting the camera close to the subject and staying wide with your lens choices. If you try and zoom underwater your video will become soft.
