i have built my own reactor and have been useing if for a while now.. however i never see any air bubbles leaving the bottom of the VAC tube.. but the chamber doesent seem to fill up as if it were not escaping. and none is leaving the top, i have a block of sponge and above that i have some inert teddy filling i use the sponge to hold it in and prevent the pump blowing it out. is the co2 dissolving ? or should i reconsider what im useing as a media. its only a small powerhead that sits in top but many attempts have either blown out the media. or the media has let to many bubbles free. fast rising or large bubbles.
my plants rarely perl. but im yet to question that once the new lights are established.
