Hello everyone, I think I am going to break down my entire tank, as I am begging to try a new engineering project (open face, salt water tank). I am selling a Dupla c02 system for now, and maybe underwater Dupla heating system, or entire tank setup - have not decided yet. If interested, please check out my digital pond project page with all the pictures, specs, commentaries, etc: http://kangar.eu/dpp.php . Pictures are located there, including a Shiro Utsiri (black/white) koi from Yokohama, also for sale, who is too big big for my indoor setup. He/she needs to go long before anything else does. - mike _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
