| | External CO2 reactor questions - flow?
I'm currently running an Eheim 2213 on my 20H. Connected to the output of this is a Tetratec 5W UV clarifier. It doesn't seem to slow down the flow from the filter much once all the air is belched out of the UV (after a filter cleaning).
I want to install a Barr type CO2 reactor that I just built. It's made with 1.5" PVC and is 18" long. At some point in time, I would like to install an inline heater as well... but that's off in the future.
I'm getting a used 2213 soon. Could I use this just stuffed with filter floss to run the reactor and someday the heater? I'm not thinking that the 2213 would have enough flow even for the reactor.
One other option I'm looking at is getting an external pump. I found a Mag Drive 5 that pushes 185 gpm at 6'. There would be some drop in this if it sat on the floor under the tank and went into a 18" long reactor. My tank is only a little less than 4' off the floor.
My last question; will this be to much flow for the 20 gallon? I'm kind of hoping that with the reactor and someday heater that the flow would be greatly reduced and not "blow" the fish and plants all over the tank.
Thanks for any help,
