UV sterilizer ?

[B-Fit]

At what flow rate will a 25w UV sterilizer be effective in killing off parasites? I'm trying to determine what size pump I will need for a pentair which is rated for 760gph max flow. It will be hooked up to a 125g with a 55g sump.

 

Thanks

Check with the maker, and lean toward the lower end of the range they suggest for a saltwater tank. Each one is different.

 

I run about 200 GPH though the one on my QT tanks.

I have e-mailed the maker two times and no reply from them. They don't have a posted # that I can call or atleast I wasn't able to find one. For now, I have a mag 7 connected to it but I'm looking to connect a mag 3 soon. I can't seem to find anywhere the optimal gph/watt ratio for parasite death. Well, thats the plan for now.

What brand is it? I run my Coralife 18w around 90-100gph. That's what they recommend for their UV. I'm going to guess that a Mag 3 is going to be too much.

Look harder....

There are several charts like this available. Keep in mind though your bulb will lose 25% efficiency within the first 2 months of use. It is common thinking to run 1/2 the recommended GPH through the unit to account for the bulbs wear and tear over the course of a year. So basically your looking at 75gph. Since this is less than 1x your system volume it means the sterilizer you have is undersized for your system. To get the full benefits of UV you are going to need something along the lines of a 40w minimum for parasite control.

Dan,

You are the man . That is what I've been looking for. I can't believe it was on Drsfostersmith site. I think I need to upgrade

 

Thanks guys
