here's my plan..hook up the external pump to choop up the big bubble from the reactor .external pump will plug to co2 controller together with solenoid, so when co2 kick in the pump will turn on ,
problem : the co2 reactor is feed by the fx5 , every 24 hours cycle the fx5 filter will shut down by it self 1-2 min max then re-start again
by any luck the filter will shut off when the solenoid and external pump are on , external will push out the water out of the reactor and running dry .
do you guys think thats worth to do it ? i dont know if that gonna acffect the external pump in the long run..i know for sure all the pump the mfg recomment not to run dry period
thanks

If this is on the output side of the canister won't it just continue to pull water from the tank even if the canister is shut off?

i dont think its gonna pull thought steve... it might take a big pump and high head to do that . the external pump i planning to use is only 150gph,1/2"pvc and the reactor is 2" pvc pipe.

I dont think it will run dry even then since it will still pull some water through. It will likely strain the motor a bit.

A couple of minutes will not hurt any pump to run dry. Ive seen really large heat producing pumps that run dry for days, melt their plumbing and still fire up just fine. Now of course it shortens the life of the motor considerably running dry that long, but a couple of minutes wont hurt a thing.
