About Yourself: I have been in the hobby of aquariums and such my whole life so about 25 years. I used to work in a LFS and am very learned on the subject. I even make green water. ;-) I have had every major kind of tank and now just like to dabble it's funny I just purchased a brand spakin new 75 for my two feeder goldies. How bad is that? I have 8 tanks.
