Hold the phone! Need some answers before we can help you...
1. How long has this tank been setup?
2. Is that an internal sponge filter in the corner?
3. Do you have any flow in that tank (power heads, return pump, HOB filter, anything?).
4. Is that an angel I see in the corner?
5. Is that a piece of rock or a wood on the sandbed? Is it live or fake? Same with the plants?
6. Assume that is a stock light?
7. Where did you get your sand from and was it live sand or dry?
8. What kind of water is in there? Premixed SW or did you mix it yourself?
If the answers to the above are what I think they are you have some work to do before you can make your tank "pretty". Not flaming you, just trying to help. Provide us with more info and we can help.
