Checking Flow Rate

Is there a way to check the flow rate. I have my uv sterilizer hooked up and I want to check the flow so that I ensure that it is not too fast or too slow.

Thanks
Christina

You can always get a container and let the outflow run into it for one minute and measure the amount of water to calculate the flow rate per minute. Fairly simply, but make sure you have enough room to handle the flow for the one minute plus some extra just in case.

Or

Take something with a known volume. Lets say a 1 gal jug. Time how long it takes to fill the 1 gal jug. Then take that time and you can calculate out the GPH.

I agree that this is another way to do it, but the only problem is when the gallon fills you have to be kind of quick to stop the flow or water can get everywhere. With that said, I think these are nearly the same method with a slightly different twist.

a UV should not have a huge flow thru it so a 1 gal jug should take 20-30 sec to fill.

If the flow is such that the jug would fill quickly then you could use a 5gal bucket. But if using a bucket know that a 5 gal bucket holds 5 gal when the water level is a few inchs below the lip.

How many watts is the unit? The size of the bulb determines the amount of flow usually.

For an average size aquarium/uv setup I'd say around 200gph. They usually say twice or three times this much on the box but I think slow is better.

It is a 9 watt is that what you need to know? so 200 gph would be best at how long of intervals, I know some people put them on timers so they don't kill the beneficial bacteria do you guys do that?

Thanks again

The manufacturer should have a recommended flow rate for the most effective kill exposure. On a 9W unit I would go for a flow as slow as I could make it.

Benifical bactera dont find their way into the water column that freqently and since only the items that can be exposed to the light will be affected by the unit you dont have to worry about it affecting your bactera for filteration.
