Teena, give me a call, I was in the Pest control Industry for 15 years, and there are some things that it will help you to know going into this.
They can take care of this without it affecting your tank, just make sure that you know your rights and what you expect from the company, especially if you are under a contract.
I actually left the industry as a whole strictly because I saw it turn into an industry that had turned into a largely unregulated racquet in this area!! Do not get me wrong, all companies are not dishonest there are some good ones I just no longer chose to be a part of it.
Sent you a PM
