Hi saldayan1!! Welcome to the forum
I would suggest that you read the sticky article on Cycling your Aquarium.
The article is located at the top of of the forum posts. You are setting yourself up for frustration, and continual problems by not following this crucial step and clearly your lfs did not caution or provide the advice you needed to start out and be sucussful.
This needs to be your first priority. We on this forum would prefer that you cycle your tank without fish, as some will probably die in the process.
Regardless you need to do this first, it takes about 4 weeks.
Let us know what we can do to help further.
Regards,
Jay
