The Industry's First HOB Filter with UV Clarification
 
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?

Questions about Aquatop's PF-UV HOB Filter
 
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!

Where can we buy them?

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

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

AquaTopMAG 07-30-2012 08:42 PM

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/cm˛.

AquaTopMAG 08-06-2012 04:11 PM

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.

UV Questions
 
All great questions! Let's take them one by one.

1. Yes, you are correct in that both good and bad bacteria are affected by UV Sterilization and that the microorganisms must pass by the UV Bulb in order to be killed off. Any bacteria that are attached to the surfaces within the aquarium or filter will remain unharmed. The second part of your question is also a yes. The primary function of our UV products is to act as an aid to inhibit algae growth. If you are establishing the bacteria in a new tank set-up, then UV Sterilization is not necessary since there should not be any algae present in your tank.


2. The Aquatop PSE-1 is primarily a Protein Skimmer with the added benefits of UV and a filter. If you are only looking for a UV Sterilizer, Aquatop recommends the UVE-7 or the SP Internal Filters with UV.


3. Yes, Protein Skimmers are primarily used in Saltwater setups due to the excess organics that accumulate on the surface on the water. They are very rarely used for Freshwater setups and would only be used under special conditions.

Hope this helps!

Thanks for the info.

This was for a friend. She wanted the setup like the PF40-UV, but needed it for a 55g tank. That's why I started looking into the PSE1. She has a canister already setup (fluval) and wanted to use the hob as a mechanical filter and also wanted UV to attack any bad bacteria.

Do you make a UV hob filter big enough for a 55g? Or would the PSE1 be it?
