I don't have any reactors in my system and can't afford to get any for a while, so no, I haven't really thought about trying to put them in there. At the moment I have them in front of a PH.

Unfortunately I can't really test for phosphates or silicates. The phosphate test kit I have is very unrealiable (hagen) and again I can't afford the $50 the LFS wants for the Salifert kits. (I haven't gotten around to ordering anything online for a while) My tank basically only has a couple hardy leathers, shrooms and zoanthids so I'm not as concerned about phosphates/silicates as I would be if I had any more delicate/sensitive corals.

I haven't had as much algae growing in the tank as I did before using the purigen so I do think it's helping the tank somehow, but it could also be coincidence that the algae is better under control now. I have been physically removing as much as possible ( I believe I have terf algae, should get an ID on it to be sure) and it's not growing back nearly as quickly as before.
