Enough oxygen?

[Melissaann0617]

Last night I removed my hob filter and set up a canister filter. I have 1 750 koralia pointed at the surface to help with gas exchange to provide oxygen. The hob also helped break the water surface. Will a 55g FOWLR be okay with just the koralia breaking the water? Right now the only inhabitants are a o clown and a couple snails but I plan to add more in the near future.
