I have read a few posts on the site about Seachem PhosGuard, most of the threads end up in a discussion of PhosGuard VS GFO - does PhosGuard leach aluminum or not, etc, but I have a different observation / question. I am running PhosGuard in a Phosban reactor, slight tumble, I notice a large yellow/white buildup in the exit hose from the reactor. My guess is the PhoseGuard is breaking down in some way. If I am seeing this build up in the exit hose, how much is settling in the aquarium as well?
Are other users of PhosGuard also seeing this?
