Recommended Needlewheel?

My CO2 reactor is not quite keeping up. It's taking a few hours to bring the pH down in the morning. I'm thinking of replacing the rio 600 rvt I have with a proper skimmer needlewheel. It will allow me to hard plumb my reactor properly since it would have an NPT thread and use a larger tubing size as a result vs. just trying to fit a short bit of tubing around it. I'm considering one of the Tunze hydrofoamer units but the DC needlewheel pumps I've seen are interesting. Largely from the standpoint of keeping AC mains voltages out of the tank moreso than any adjustability I would gain from it. I'll probably also put some hydro sponge foam in the reactor as well to help provide additional turbulence to help dissolve the CO2 a bit more as well.


Has anyone been using the skimmer needlewheels and how have they been working out for you?
