• Our own custom product, designed for easy service and installation. LONG water contact time!!
• Works well with canister filters or any pump/ filter or diverter with a flow rate of 150 to 350 gph (a larger pump may be used, we recommend diverting the water for a slower gph for maximum effectiveness of this OR ANY OTHER UV).
• For aquariums up to 200 gallons or ponds up to 1000 gallons. It comes with 1/2" hose barbs [convertible to 5/8 to 3/4"], an adapter for hang-on-the back applications, and a 15 watt in line uvc bulb.
• The best part of this units simplicity is that you can also obtain the 'o' rings at most hardware stores and you can obtain the uvc bulb [the unit comes with one] at many pet stores [coral life makes a good one].
• This UV also comes with a durable magnetic ballast, as compared to most UVs that come with cheap electronic ballasts that last only a year or two. We use FS-2 starters that are easy to find, cheap to replace (unlike expensive hard to find electronic ballasts). In fact in over 15 years of building these and 100s built/ maintained we have yet to replace a ballast! We also sell these starters in our shopping cart below.
• Requires 110/120 V or an adapter. (If you live outside North America)

• This UV can be either installed in-line (such as with a Canister Filter or power head), placed on a valve controlled bypass, or hung on the back as shown in the picture to the left. For HOB applications where an internal power head/pump/filter is used, I recommend the purchase of the intake adapter which is sold separately to keep tubing in from the aquarium from “kinking” (the intake adapter is shown in the picture to the left as well).
• This UV Sterilizer/Clarifier uses ½ inch to 5/8 inch ID (inside dimension) tubing. We recommend a pump with at least 4 feet of head pressure to adequately “push” water through this UV, even if hung on the back.

*Easy pond installation; simply remove the hose barb and 1/2-3/4" reducer, replace with 3/4" nipples, connect to return lines in your pond via 'T's in your existing PVC and 3/4" reducers from whatever your return lines diameter.
