I don't have a reactor. Phosban can be added directly to the tank, can it not?
I'm trying to keep my setup fairly simple (plus, I've got jack for $$), so I don't want to buy any extra equipment.
Thanks for the ideas and comments. KEEP'M COMIN!
I think you have to have decent flow going through the Phosban. Maybe in a filter sock on your overflow, but I think if you just throw a bag of it in the tank then it won't do much.
I could be wrong.
