I'm not new to the forum but inactivity has made me forget my old password. (New account) I have a 55 gallon freshwater, semi-aggressive community. 16 gallon freshwater peaceful community, and an 8 gallon pico. Will be upgrading to a 75 this summer to accommodate my plecos. (I'm a pleco addict) anyway, looking forward to seeing all of your set-ups and learning some new things
