Hello everyone. I'm new to this forum and I'm still very much a novice to reef aquariums. I'm having an 80 gal AIO custom reef aquarium built to my specs. Before this I've only run nano reef tanks , 2 15 gal columns and a 29 gal. I'm deciding on my equipment at this point in time and would like some of halls thoughts on what I've chosen. So far I'm going to run 2 Sicca 3.5 664gph pumps, with one 4" sock filter in one corner of the overflow and a filter medium cartridge in the opposite corner. This will give me a flow of 1224 gph with 4 adjustable directional nozzles. I've yet to choose a protein skimmer still deciding whether external or internal yet. I know you should average between 8-10x your gallon capacity for your filtration flow but would like to run a Lil extra for those corals that need a Lil more flow. Please give your opinion on this as all input will be appreciated. Ty
