CO2 & Reactor Flow Rate Problems
If anybody can help on this one it would be appreciated.
I am working on getting an Ultralife CO2 system fired up and am having
a water flow rate problem (?). Ultralife recommends that a 60 gph pump
be used to push the water through the reactor. I purchased a EHEIM 1048
that has a rated 158 gph with a 4'11" delivery head. I believe that the
flow rate is way too fast with this type of pump as I am having a hard
time pushing the CO2 into the reactor (I even tried blowing air into it
myself and it was almost impossible!). During the startup and adjusting
it looks as though I blew the Ultralife check valve from the high back
pressure.
Has anybody else run into this? My next step (I got a replacement check
valve with emergency spares) is to try and reduce the flow rate to get
it closer to the 60 gph that Ultralife recommends to see if this takes
care of the problem. Any recommendations on how to get the 60 gph out of
a pump that is rated at 158 gph with a 4'11" head? I saw a chart
somewhere that gives hose lengths and delivery head adjustments in order
to get slower flow rates but can't seem to remember where I saw it at.
This entire system is being installed on a 125 gallon tank.
Any helpful information and/or suggestions would be welcome. Thanks!
