Are you concerned about CO2 absorption? I'm assuming you're using an inline CO2 diffuser if that's the case.
If the inline one doesn't work out for you, you can easily swap it for an in-tank one. You'll just need to clean it more often v.s. the inline one.
You may even find that you prefer the in-tank one, as it has larger bubbles that rise to the surface more quickly, allowing the water to be clearer (i.e., less hazy from all those micro-bubbles). You'll have less CO2 absorption though, and you'll need to use more CO2.
Oh well... there are always trade offs.
