I have a 8 Gal LPS dominated reef tank. I'm planning on building the sump. I already have the tank for the sump which is a 5 Gal tank. My question is, which protein skimmer would fit best in my sump ? https://www.tokopedia.com/aquastop/jebo-178-protein-skimmer https://www.tokopedia.com/ikansapoesapoe/resun-protein-skimmer-sk-300 https://www.tokopedia.com/abfaquatic/protein-skimmer-resun-sk-05-aquarium-laut P.S. I'm picking these not because they're cheap but rather because these are the only ones that can fit in my stand.
