i have found several sites / plans for building a external reactor but, none of them explain how to plumb it in. i assume a bypass is used but, i have no clue how to set such a thing up.

could someone point me in the right direction??

actually, i had already searched out your thread there.

it doesn't just blow the co2 out the bottom ... i have an eheim 2026 and it just seems like it would over power it.

Nope. I have 100% absorbtion. Actually from the clear reactors I have seen the CO2 is completely absorbed by about 4-6 inches of tube length depending on design.... You would be suprised how well they work....

Due to the increased diameter of the reactor, the water slows down, which keeps the bubbles floating until they are dissolved. For a higher throughput, the diameter needs to be sufficient, or you could indeed see the bubbles coming out on the other end. :shock:

I'd say, with a 2" diameter you should be fine. I "tried" a 1.5" diameter, and it was not enough for the XP3 that I connected it to.

I have it hooked to a XP-3.... 2 inches is pretty much the norm for reactor diameter, tho your mileage may differ.
