Deltec Calcium Rector pf 501

[jai_1206]

Hello, I have bought a new calcium ractor pf 501 yesterday and when I set it up I can see co2 is getting collected at the top of the chamber and slowly pass through effluent out hole , it can be heard by hissing sound coming from effluent with air coming out. Shouldn't this extra co2 be recirculated? I think the inlet for pump suction is few cms long and co2 recirculation is not possible because of it and instead it goes to effluent hole. Is this by design or something can be done? Any ideas?
