Great lil build thread for a pico. I kept a pico in my old office for about 2 years. I didnt do any mods or anything just added a lil mini jet for more flow.
I successfully kept tons of xenia, zoas, rics, and some shrooms, never kept a fish in it but did have a cuc. I did go bare bottom though. I figured the sand would have been a nitrate bed. I never fed the tank, I always added tap water, best of all I NEVER did water changes. After two years it was jam packed and self maintaining. I almost never had to clean it cause my co-workers would come by and clean it for me.
I should have taken pictures before i was laid off.
