to get back to topic all we are telling you is keeping a marine aquarium takes allot of time, patients, and work. not having the proper equipment will cause all of this to be longer and harder and possibly make u hate and quit the way of life as i like to refer to it as. some call it a hobby but its much more than that is a job u love to hate and hate to love at times. but is one of the most beautiful things u can have in your house.
