Hey there ! You have stumbled upon my little-big reef tank !! Going to describe my setup & share some tips ALSO looking to get some thoughts/opinions/comments going ! Here it is ! Will post some pics soon. Also, i do run a SUMPLESS system ! I know the drawbacks of going sumpless, but i cant afford one & am on a budget ! So thought i'd share this for all you budget reefers !! Lol • 90 gallon glass tank • Fluval Fx4 canister filter • HOB 10 gallon refugium with macros • reef octopus bh-1000 protien skimmer • aquamaxx medium media reactor • mixed reef • some tangs, fire fish, clams, frags, pipefish & ALOT more !!! • inch thick sand bed • 10-15% weekly water changes a MUST for sumpless systems to avoid your canister filter becoming a NITRATE FACTORY lol ! Comments ? Opinions ? Again will post pics in a sec still kinda new to this !
