I run two for my 36 g. Diffusing one with an airstone and the other with a diffuser. And my fish are okay just so you know and do notice growth of plants idk about your 55 g tho, sorry.

Oh and make sure to have a drop checker to measure your co2.

I think you should just run one for each tank, but with staggered bottles.
