Hi.

I got the 40w pondmaster UVC. My goal is to use it as an sterilizer for my 186gal total water volume w/o water displacement Tank. Let's say that the total water volume is between 160 and 170 gallons approx. I understand that flow, contact time versus wattage is the key to get the desired results.

I will like to achieve level 1 or 2 sterilization. So it could help me prevent or at least control parasites and protozoa in my Display Tank. The unit is plumbed to a manifold from the return pump but the Uv empties directly into the DT as recommended for optimal efficiency on circulation. I have a flow meter sensor that I can monitor the flow going into the UV chamber control by a gate valve for fine turning. My problem consists on how much flow I need to pass by the UV chamber to achieve my goal. I look all over the net and forums and I ended up with more questions than answers.


I'm writing you guys to see if you can help me out here. I know there is a mathematical formula, but I'm confused on how to apply it in order to get the right flow. Maybe you could suggest me what flow rate should I push thru the UV chamber to get the best results for what I want.


I appreciate your help.
 
My pentair 40w recommended 240 gal/hr flow rate so I run mine at 200 gal/hr.
