APS Filter Booster

[Daveslaney]

The people using these after thier inline diffusers as a co2 reactor, did you plumb them in the normal flow direction as shown on the box? in at the bottom and out at the top?
Or is it better to plumb it counter current in at top out at bottom? This way the co2 bubbles will try to rise to the top against the flow so should dissolve better?But may lead to co2 becoming trapped in top of filter booster?Causing a air lock.
Going to plumb mine in tomorrow.

Plumbed it in the regular flow way. Removed the foam from the filter booster put a hand full of plastic bio balls in.
lime green drop checker with little loss of flow and no co2 mist in the tank .
