Hi i have been maintaining a freshwater and a saltwater tank for just about 4 years now. But since i am in high school now, the work load increased dramaically and i found less time taking care of both my tanks. After some thought, i decided on selling my freshwater tank. I am only a freshman, so if i think the work is hard, imagine when im a senior.... Dont get me wrong, all of my fish are healthy and alive. I just ended up working late, changing the water and trimming the plants. I just wanted to thank everyone for helping me the advice for a full four years. I will continue with my saltwater tank, and continue using this site. However, i think i will only b able to continue my marine tank for another four years because of college. Again thankyou to everyone in this forum.
