Just wondering if anyone out there can identify these small beads. I think they're filter media of some sort just not sure what. Thanks in advance for your help!
i just bought some phosguard today so kind of cheated a bit on this 1 lol
Incase anyone is wondering what phosguard does its basically same as GFO except it uses some type of aluminum ionization.
It is less efficient and slightly more harmful than GFO, Its only benefit is that it works better when run outside of a reactor. Aka i am going to use mine on a HOB filter
Looks like seachem’s phosguard to me. I used it twice not sure if it actually did anything. Put in high flow after 4 days it should have absorbed any phosphate that runs through it.
