no biggen think ya missing what im saying !! yes if ya cap the airline to the box then yea it would fill with air and slow the flow for sure !! but if you just disconnect the air line from your ph and let gravity take its course ya dont lose any water flow!! and it still sucks out the air thats trapped !! but the ph has no effect on the water leaving the tank! if your pumping in 600 gph in your tank 600 gallons will flow thru the box and very very little goes thru the air line !! the way u explained it,it would sound that with out a power head your tank would overflow !! only if the air line gets clogged and cant pull out the extra air or a power outage !! it is safer to use with a ph for sure no doubt but has nothing to do with the flow !!

also if ya think about if ya start a siphon with an air line tube how long does it take to drain a 5 gallon bucket??? like 30-40 min !!! so no way ya tank water line would raise just cause ya not using a ph !! i run 2 cprs one has a ph the other in the basement on a gravity feed !!

not a biggy just disagree that a powerhead hooked to a 3/16th line pulls enough water to make a diff !! if anything ive found that the one with the powerhead get more junk stuck into the airline than the one thats on gravity !! due to the exrta force it trying to suck anything into it !! and imo nomatter which way ya set it up ya have to keep a close eye that all is well for sure !!
