Pond UV Tips

Pond UV Clarifier Tips

* UV Clarifier/ Filter placement
A UV Sterilizer/Clarifier works best when the UV is place AFTER the filter. I know this contradicts some information I have read and this information is not necessarily wrong either, so let me explain further; By placing your Clarifier after the filter, you will remove debris that will otherwise make penetration of UVC light difficult, further more in my experience this will greatly reduce the amount of sludge buildup inside your Sterilizer/Clarifier, I will also note that the gimmicky wipers do not help much with problem. The reason some pond keepers recommend placing the filter after the UV Sterilizer is to trap algae that often clumps after passing through your clarifier, so as I noted this suggestion is not without merit. However in practical experience (along with knowledge of how uvc works), I have found that in an either or situation, the first suggestion of placing the filter first works best, this said, a pond keeper can always employ both methods for even better results, although even here I find this to make no discernable difference as to clarity, only to the amount of detritus/mulm buildup in the pond (of which controlling this via whatever means possible is certainly useful to good pond hygiene, although pond vacuums can be a useful tool here as well).

*Filters
This really goes without saying, but I will state the obvious (at least in my opinion, so please do not be insulted by my stating this point this way), USE ONE OR MORE pond filters.
Often I have had persons tell me that they bought a UV Clarifier only to realize that the new pond keeper figured the UV Sterilizer would take care of the Green Pond all by itself, which it will not. I strongly suggest a Veggie Filter in addition to a more traditional Pond Filter such as the Clear Stream Pressurized Filter, for further information about this subject, please read this article: “Aquarium and Pond Answers; Veggie Filters”.

Flow Rate
Maintain a proper flow rate to your UV Clarifier/Sterilizer either by using a slower pump or splitting the flow from your high GPH pump so as to send water to your UV at a slower rate. This is a common problem in poor UV Sterilizer installation, but easy to solve. This flow rate should be around 20-40 gph per watt, please see my Full UV Sterilization article for more about this subject: “UV Sterilization; how it works”

Do not waste time or money on gimmicks
I will not waste space addressing this other than stating gimmicks such as wipers or “twists” do little to improve UV Sterilization, other than lightening up your wallet.

Maintenance
Clean your UV Sterilizer unit with each UV bulb change, which for a pond should be every season or every six months in warmer climates such as Southern California, Florida, Texas, etc. Make sure models with a quartz sleeve get the quartz sleeve cleaned as well, especially of hard water deposits (which wipers do little for).
