Juwel OxyPlus O2 Diffuser in Singapore Tanks

The OxyPlus O2 Diffuser connects to a Juwel internal filter and pushes fine bubbles into the flow, lifting dissolved oxygen without needing a separate air pump. This is genuinely useful here because warm water holds less oxygen than cool water, and our typical 27-29C tanks sit near the low end, so a stocked community tank benefits from the extra gas exchange and surface movement.

The output is infinitely adjustable, so you can ease it up during the hottest afternoons or turn it down at night, and it slots straight into the existing Juwel filter system without modification. Many of our customers run it gently on planted tanks during darkness, when plants stop producing oxygen and start consuming it, to keep fish comfortable until morning.
