Hi Everybody, Im Rod and new to this group, Im also new to the ideas of Sumps, before I ever if ever move to the expensive Saltwater setups, Im staying with my brought up love of Cichlids and as a whole the standard (haha-anything but) tropical tanks. Yes I have done a fair bit of research, though applying what you learn to what you do can lead to some oversights. I have acquired Display Tank Tank Dimension (inside) 150 x 66H x 57W Tank Size (L) 564. litres /150G so the total project is for my 12year twin boys, starting from scratch, we even Built the stand (building) from the plans of Joey (KingofDIY) as my twins are avid followers so in a way we are kind working in reverse.. since we have no clue what fish we will end up with in such a bloody big tank ...for us it is. So with my years in aquariums be it limited to simple cannisters etc this is our new and next project. designing the sump drilling the tank and well finishing the cabinet as we go. Following this will be doing automatic water changes system, and diy lighting, with a diy auto solar preheater and solar axcillary powersystem...step by step so clearly months and months of designing to come for each stage.. but firstly Can you guys please give me feedback with my sump design.. will it work? won't it? and pro's con's I have attempted to create a kinda reasonable attempt of a diagram for you to look at with its details Thanks a tonne in advance.
