The Industry's First HOB Filter with UV Clarification

[AquaTopMAG]

The word is spreading about our PF-UV Series. Great hang on back filters.


• The Industry’s first Hang-on Filter with UV clarification
• Motor and UV include independent switches
• Includes self-adjusting, built-in surface skimmer
• For Fresh & Saltwater Aquariums up to 40 Gallons

These would be awesome for greenwater outbreaks.

I have questions.
What is the warranty as UV deteriorates many plastics?
How are the UV specs determined?
.....Dwell time (time the water is in contact with the UV bulb sleeve) is the single most important factor in a killing dosage.
What keeps the UV from killing the bacteria in the media?
Is the UV source on a separate switch or power cord?

Great questions! Let's take them one by one.

1. What is the warranty as UV deteriorates many plastics?

The UV housing of the PF-UV Series is constructed of UV-resistant plastic ensuring longevity. Our products are under warranty to the original purchaser against defective material and workmanship under normal use for a period of 180 days from the date of the original purchase. Rest assured, however, that the UV housing of the PF-UV Series, if treated properly, will last for many years.

2. How are the UV Specs determined?

Dwell time (time the water is in contact with the UV bulb sleeve) is the single most important factor in a killing dosage.

a) All UV specifications relative to AquaTop products are based upon rigorous, long-term testing with qualified spectral output equipment.

b) Dwell Time can be calculated by measuring the distance between the bulb and the quartz sleeve, the distance between the quartz sleeve and the interior of the UV housing, the thickness of the UV sleeve with flow rate taken into accountability.

c) UV products by AquaTop offer adjustable flow rates allowing for a user to increase a kill rate or decrease a kill rate and are typically set or rated for a kill rate of 30,000µW/m2.

3. What keeps the UV from killing the bacteria in the media?

a) No worries on that end. There is a UV housing that keeps all emitted UV rays from coming into contact with the filtration media.

Hope this helps!

Do you have more precise lifespan of the protective UV housing? I'm just a little paranoid about UV Also you mentioned "if treated properly," what will accelerate the deterioration of the protective casing? Thanks.

We understand. UV can be new territory for many hobbyists and we encourage customers to do their research. The housing in the unit is designed just for UV and while we can’t give you a specific lifespan, we can tell you confidently that as long as you break it, the housing will last for years. Bob Goemans just published a book and he addresses UV technology very thoroughly in the filtration chapter. There's some great information from one of the industry's leading authorities Here is the link:

That dose won't kill much of anything. Did you omit the c in cm?
The kill dosage for Salmonella, for instance, is 10,000µW/cm².

[AquaTopMAG]

Yes! It should be centimeters squared; cm with the number 2 superscript. Good catch!

If I am understanding how UV works. It will kill all bacteria, but the majority of good bacteria that are needed for the nitrogen cycle are not affect because they are on surfaces such as bioballs, in gravel and not free swimming, therefore not going thru UV rays? Would you avoid this type of filtration while trying to establish the bacteria for the nitrogen cycle?

Also, looking for one that will be powerful enough for a 55 gal tank. So, would it be your Aquatop PSE1? This is a mechanical filter as well as a UV & skimmer.

Lastly, this is for a freshwater tank. Is skimmer used solely for saltwater setups? Any use in freshwater?

Thanks for clarification.

Wow, very interesting. I'm loving how far this hobby is coming just in the past few years!

I have some 2 gallon tanks would the 15 be small enough?

I currently use the azoo STUFFED with media, on LOW. I would love knowing my betta tanks are 'all clean'.

I also have a 6 gallon tank, is this something i can 'add on' and run every so often to just clean every so often?

Does the 15 have the skimmer, while i don't have saltwater tanks, I get that 'slime' on the water top from fertz.

Hi there--Our smallest model is the PF15-UV for tanks up to 15 gallons (5.0” wide x 5.0” deep x 7.75” tall). You can also replace your current filter with the PF15-UV as it is a dedicated HOB filter but with built-in UV sterilization. A nice feature is that the UV can be turned off and on and has a separate power source. In regards to the surface skimmer, yes it does come with one. The PF15 not only comes with a filter cartridge but also ceramic rings to promote beneficial bacteria growth. This is a 5 step filtration process: surface skimmer, mechanical, chemical, UV, and biological. Hope this helps!
