I use one on my frag tank. I got it to help avoid any algae problems caused by heavy feeding and nitrate dosing. Haven't had any diseases in fish or coral since using. Is there an issue you are trying to solve with a UV sterilizer?

Hi Kelly. I got a 25 watt UV sterilizer for this build. I’m planning on low flow for disease control. About 400 gph.
Do you how how much flow you are running through yours, and how many watts?
My understanding is higher flow is good for algae control only. Lower flow gives longer exposure time to critters.
