A gravity return filter with both UV clarification and biological media, aimed at smaller garden ponds. The UV stage handles green water while SUPRA+ media gives beneficial bacteria the surface area they need to process fish waste.
Key features
- UV and biological filtration in one unit
- SUPRA+ Bio Media supports strong bacterial colonies
- Flip up lid for quick access at cleaning time
- Gravity fed return, no second pump needed
- Suited to smaller ponds
Clear water takes a few weeks after installation, since the bacteria need time to establish. Resist cleaning the biological media in tap water, which kills the colony you are trying to grow.
