ANYWAYS..
To the OP..
i have a 46g bow front i just shifted to with all my old tank stuff and all i have is a topfin-75 filter that i deep clean once a months and swap polyfill weekly and carbon cartridges bi-weekly, it keeps my water crystal clear and parameters very stable. nitrates never get about 10ppm in my tank with bi-weekly water changes opposite of the cartridge changes, i see no need for a skimmer i have 60lbs of live reef grade sand, and about 45lbs of live rock soon to be about 60lbs in a 2wks time adding in rock slowly to keep everything stable with minimal die off, i really dont need a skimmer as of now, but ill be adding one later when i get more fish, i have a flame angel, 2 caramel clowns, six-line wrasse, soon to be orchid dotty back, 2 purple firefish and a tiny-small yellow tang (1.25") so ill be using a hydor slim skim rated for 65g after all that, but for now, skimmer-less is fine
