OxyPlus clips onto the outlet of a Juwel filter and draws air into the return flow, breaking it into fine bubbles that lift dissolved oxygen. Useful in a warm tank, a heavily stocked one, or overnight in a planted tank when the plants stop producing oxygen and start using it.
It does not fit the Bioflow One. Juwel lists it for all its filter systems except that one — which is awkward, because Primo 60 and 70 owners are exactly the nano keepers most likely to want it. It also adds bubble noise and some surface splash, which Juwel does not mention.
Fitment
Bioflow Super, M, L and XL. Airflow is infinitely adjustable. Length 8 cm.
The rest of the range is in our Juwel collection.
