Look for media reactors

[Tecdiverfl]

Looking to upgrade from my BRS dual reactor on my 180. Let me know what you have

i'm using a simple phosban reactor 150 and IMO single chamber media reactors are all the same besides the name brand only difference is the size as your gonna obviously use more media for your 180 g then i would use in my 54 g
