pinwheel impeller for fluval 207

[Tonyball]

Does anyone know we're I can get a pinwheel impeller for a fluval 207 canister filter?
Thanks

I expect you'll have to make one as I don't think pin wheel impellers are used in canister filters often, if at all.
I'm guessing you want to use your canister filter as a CO² reactor. If that is the case there isn't any need for a pin wheel impeller. I have a diffuser that sits below my filter intake and I have no bubbles visible in the tank with only the occasional squeak of undissolved CO² escaping via the spray bar but most gets dissolved.

As above, if it is for CO2 it's not needed. I inject my CO2 into the intake without a diffuser at all and it works a charm.

I just tried this with a 307 and 200l tank so fairly higher injection rates.
Would burp about once every 30mins at a rough guess?
No bubbles in the tank which was nice but the burping was anouying so switched back

I second this. High injection rate with a fluval 407 on a 180L tank here. It kept burping and expelling the co2 buildup... kind of counter-productive as a reactor. I decided to build a cerges reactor and haven't looked back since.

From experience with the 407 you can generally put 3 ~4 bps into the inlet without it constantly burping, anything more than this and you get the hourly annoyance.
