This tank was given to me by a friend who was moving. At first it was more of a pain than anything because it kept going cloudy. Once I purchased a proper filter it looks better now. It's a freshwater tank and the red guppy you see is the boss. He chases the others and bites them if they get too close. I was offered an Integ system if I would post about it and help spread the word. I really like how I can keep track of the temperature and receive notifications if the tank gets too cold. One day at work I got notified on my phone the heater wasn't working and when I came home I realized the power bar was switched off. I could see this being a really useful tool for larger systems.
