Hi there! I am new here, as you can tell. I am a high school science teacher (for my job), and am somewhat new to the aquarium world. This is a hobby that I have taken up with my youngest daughter (10) due to our love of marine biology. I currently just have a small 5 gallon tank and a 20 gallon tank. I would eventually love to work my way up into saltwater aquariums, but decided to start with the more economical freshwater tanks for now.
