Hi letting go of my old Reefbot. Many newer replaced parts. Extra bottles, vials, stirrers,needles. I used for a couple years with moderate success. Replaced several parts but don’t have the time to tinker anymore.. was working last time I used, but just selling as a fixer/parts machine. newer dosing heads/motors,test chamber..everything I have included, all parts. Will be Shipped in original packaging. Please let me know if any questions or want any more pictures. Thanks!
