Custom 15 Watt UV Sterilizer/Clarifier- $125.99 Pre-Order

Purchased via an invoice, not our checkout system since this is a custom built product which requires a contract between AAP & the buyer for liability, as we no longer carry insurance for manufacturing.
Economy shipping is not an option for invoiced products, only Standard or higher shipping methods, but then better shipping is recommended to this first rate product with years of professional use behind it.

Currently due to health issues for Carl and lack of time due to his time spent in forums, outside work, simply a very poor marketplace making time building these UVs not time well spent, and especially insurance costs (we cannot afford the risk to build without insurance), these custom UVs have been discontinued.

UV Sterilizer Experts • Our own custom product, designed for easy service and installation. LONG water contact time!!
While a time consuming product for AAP to still build & sell (with low profit when time is factored in), we still have continued to sell this item only due to word of mouth & popular demand (we do not advertise this product). This is also why we only sell this Standard Shipping and higher rather than take the losses & risks of Economy Shipping as well no costly phone orders too (yes phone orders do cost us more to process both in time and higher merchant CC fees).

Recommended only for those (& DIY types) who want a unique custom product based on decades of professional experience, NOT for those who want a product that is sleek and cookie cutter in its design & fit.
Due to the limited time to produce these UVs, we reserve the right to refuse sales for those this would not be a good fit.

• Excellent UVC Penetration with only .2 to .3 cm between UV lamp and the inside all of the unit for Mw/cm2 intensity factor of near 300

• 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" -5/8 hose barbs [convertible to 3/4"], an adapter for hang-on-the back applications, and a 15 watt in line UVC bulb.
Design limits flow rate to 350 gph (which 150 to 350 gph is recommended for optimum results)

• 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.

Custom UV hang on the back
• 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) Aquarium/Pond Vinyl 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.

*Bulb FS-2 Starters - $3.99 Jump to Shopping Cart
(Usually when the bulb fails to light upon replacement, this is the problem, which is a simple and inexpensive fix and can also be found at many hardware stores too)

1" compression 'O' Rings for UV Sterilizer $2.99 set
*I recommend replacing them at least every other bulb change, these also may adhere to the bulb upon changing the old bulb out and need to be gently loosened with a small knife, otherwise replacement of O Rings becomes necessary

Aquarium & Pond Plumbing Parts

*UV Water Return and Intake Adapter
For use with Vecton, Terminator, or any other under aquarium UV Sterilizer. For use with in-tank power heads or internal filters to safely return or intake water to the aquarium without hose kinks.

*3/4" X 1/2" (TO 5/8") Hose Barb Adapter
Useful for adapting 3/4" inch hose barbs on UVs (such as the 9 Watt Terminator) or other aquarium equipment to the 1/2 to 5/8" hoses common Ehiem and other filters.
FOR EXAMPLE; to fit a 9 Watt Terminator to a Fluval 404 Filter, you would splice the out flow tubing and connect the 1/2 to 5/8 barb to the filter tubing on both sides and the 3/4" barb would attach to the Terminator (in the middle of the outflow).

*Water T Diverter Valves
For use with ponds, sumps, or any high flow water application where the flow rate exceeds the recommended GPH per watt for a UV Sterilizer as well as other applications

I hope you could share this on your website. I was looking for pictures like this all over on the internet. Now I took them, to share them with others having the same problem. Thanks again.
