Injecting CO2 into pump?
I have read numerous ways of dissolving CO2 into the water including using glass diffuser,flipper and CO2 reactors. I know glass diffuser or flipper not as effective as reactors.
One bro told me he injects CO2 directly into his Eheim filter. Seems logical. However, i am using an overhead filter and think of just letting the CO2 being stuck into the pump head. Can someone share his experience if this method has worked? Thanks. |

so long u allow the CO2 to travel through a tube to the filter, the longer the tube, the more CO2 is dissolved..
1 thing to take note.. if CO2 is not well dissolved, especially for canister filter like Eheim, it will cause the filter motor to wear off faster as CO2 is trapped in his filter.. another thing to note for your case, using over head filter is not a recommended setup when CO2 is injected into the tank.. CO2 will escape especially when water is sprayed onto the filter bed before going back into the tank.. |

The co2 will come out as a bubble from your source. As you suggest, it will be sucked into the pump and dissolved into the water. go through the filter and released back into the tank.
There is not enough time for the co2 bubble to dissolve. As mentioned, the co2 bubble will damage the pump impeller in the long run. Meanwhile it will simply escape into the atmosphere when it is dumped on the filter bed of your OHF. |

if the bubble is small enough and pipeline is long enough, CO2 will dissolve well.. but CO2 will escape if using OHF.. for cannister, it is a better choice at the risk of damaged head if undissolved CO2 accumulate around the head...

Once dissolved, can the CO2 escape so easily? Seems two Bros think so. So if someone using a cannister but spray bar at its output, then the outcome will be the same too, right? Thanks... |
