220gal tank

[Giants2]

Hey everyone,

New to saltwater but been keeping freshwater fish since I was 14 now 38. Right now I have a 220gal withb2 fx6s canisters and my plan was to go live sand/rock with the 2 fx6s but dont know what protein skimmer to get since I dont have a sump and honestly never had one before. Looking online there's so much information but im kinda getting lost to the point where salt seems crazy

Forget the skimmer if you don’t have a sump. The little hang on the rim ones are not sized for your tank.

Ok so 2 fx6, live sand and rock and weekly wc which I alrdy do about 30% I should be Ok? Everywhere I read theu say I need a skimmer

People kept tanks before there were skimmers . Sumps were the solution to adding more filtration instead of relying on deep sand beds, canister filters and under gravel filtration.
With the sump you have an overflow which provides surface skimming . A fuge which can provide filtration. A skimmer is just one more level of filtration. Even with all of that water changes are still needed. ( my unpopular option )
