UV sterilizer for waterbox 200.6

[altayeh]

Hello, I’m setting up the waterbox 220.6. I wish to use the Aqua 57 watt UV sterilizer to help reduce algae. Which separate pump is recommended for this to help obtain these results. In future if I wanted to go after bacteria, what would you suggest? Thanks

If you just need it for algae, you probably only need a 25-watt UV with a flow rate of ~800Gph. You need a much higher flow rate of ~2,000Gph for algae with a 57-watt
