I have had my tank up and running for over a year. In Jan. it crashed because i went on vacation and the person who was suppose to take care of it didnt. It is a 10 gal nano, so i lost basicallyeverything and tryin to heal those that did survive. I was wondering does the tank go through a whole new cycle, like it does when you first start a tank...because i have a huge algea growth even tho i do my weekly cleaning. I am so disappointed that it crashed. any advise will help...thank you
