Difficult question. Depends on the type of fish, and amount of filtration. Larger fish require more filtration than smaller fish. Liverock/skimmer/mechanical filtration all work together. Only way to answer your question is to ask a few more. Have your checked your water parameters. Are there detectable levels of Amonia and Nitrite? How much live rock. How big is your skimmer. What kinds of fish. Any inverts(coral/snails/shrimp/crabs?
I made same mistake starting out on the fly and had to restart. First thing RO/DI, substrate, live rock, skimmer, then fish (little at a time), CUC. Corals and anenome should be aways down the road and it cycles and tank becomes mature

Both of those skimmers are HOB(hang on back). They are both name brand and either one will server you well. I have used both brands and would recommend either. As far as Powerheads(for circulation) Hydor Koralia Evolution Circulation Pump/Powerhead
