UV sterilizer

[Jose riesgo]

Hello guy I have a 400 gallon salt water fish only tank. I’m currently running a coral life twist 36 watt uv sterilizer and would like to upgrade any recommendations. Or am I better off buying just another coral life twist 36 watt and run both any advice would be appreciated

Doubling-up with the Coral Life UV sounds like a very good idea to me, for a 400 gallon tank. But I don’t know their quality. Maybe just take the plunge and get a nice beefy Pentair.
