Just finally decided to become a member on here after plenty of time snooping around, my tank setup is a 3.7 gal aio from petco, 4 pounds of live rock, 6 pounds of live sand, running imaginarium boxed sea water, and running a bag of chemi pure elite. Stock currently is 1 1” yellow watchman goby, a margarita snail, a small Xenia colony and a small GSP frag(yet to open up) I just added today(yes I know both are invasive as heck it doesn’t bother me). Everything seems to be doing good and staying stable. I’ve had a tank previously but do y’all have any advice for a first time pico owner? Anything would be appreciated. Thank y’all! I’m happy to be here! I’m sure there’s plenty of knowledge and adventure to come.
