Will backflow occur?

[Dennerle]

hey guys, now i changed my way of installation for my co2 tank already dunno backflow will occur not so need urs advise.

Co2 cylinder->regulator with needle valve->tubing to bubble counter->tubing from bubble counter to external reactor->outlet hose of eheim canister filter to external reactor->hose from external reactor to aquarium tank. From what i see there, looks like backflow impossible in this case. what u guys think?

So far backflow normally happens on systems using diffuser. For reactors I think it doesn't happen. Anyway, to be on the safe side, you can easily fit a check valve which cost very minimal.
