Purigen has long been a popular media – it perform quite unique results:
Purigen controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds.
Not only that but it polishes your water like you’ve never seen before, almost like the water doesn’t actually exist in your tank. It really is quite extraordinary.
Whilst we have always sold it in smaller sizes, now we have it avialable in the 2L version as a special order only.
