hey everyone, Back to this forum to start another upgrade build. My 108g ran out of space so i decided to do an upgrade. Probably going to run similar setup as of what i’m runing now with just skimmer as filtration. Upgraded tank: 160 gallon rimless peninsula planet aquarium 60x30x21H” with 3/4” thickness DIY stand: 61x31x38” using 2x4 and 2x6 with 3/4” melamine cover. Sump: reusing my old 40g breeder My returns is 2”, and looking at the bulkhead, the flange is 4” in diameter so i feared that im going to lose a lot of water height.(what you folks think? Anyone runn 2” for their drain? For sump, i hope i can reuse my 40g breeder that i currently have. Just hoping it can hold enough water with the new 160g Equipments: Mp40 QD Gyre fx230 Jebao rsw15 Return pump: reef octopus varios 6 Lighting: ATI t5 8x54watt with 2 reefbrite xho Reef octopus skimmer diablo 250ext with upgraded regal 300 varios 6s pump. Geo 618 calcium reactor with DIY second chamber While im waiting for the tank to be build. I decided to start with the rock scape. Great thanks to a reefer in Colorado who had a good amount of tonga branch in his procession for a great deal.
