<p>Good Post Casey!!!</p>

<p>I have not found any new information regarding UV use in Aquaponics. Most of my research was based around Aquaculture and Aquaculture with some plants in the water. The information out there about aquaponics and UV is slim to none. I reached the end of the internet on this subject, and will research it again in a few years.

<p></p>
<p>More research must be done in this aria. If you do put a UV in your system their is likely going to be benefits and some possible detriments to the system. The Benefits are substantial and detriments are very minimal.</p>
<p></p>
<p>Many People agree that UVs seem to only add benefits to Aquaculture systems. </p>
<p>Many People agree that UVs help keep a sterile environment reducing many types of disease transfer.</p>
<p>A relatively small number of people have claimed that UVs damaged their AP systems. </p>
<p>Everyone Agrees that UVs make water more clear.</p>
<p> </p>
<p>Once my system is established and i understand exactly how my system is running i will most likely add a UV to the system. This is possibly about 1-4 years away for me. Once i get to that point i will see if my system performs better or worse with the addition of the UV. For now my system seems to be doing fine without a UV</p> Lots of good comments!

<p>The Aquaponics Association Conference in Tucson went over food safety in detail including the possibility of the transfer of listeria and fish allergens from the water to the produce and the possibility that the algae slime growing on rafts could contain small amounts of toxins (apparently we should never, ever let the fish water or the slime touch the produce). Of course AP is still too new to know if any of this is actually true about AP systems, and I don't think anyone has gotten sick so far that we know of, but the idea has serious ramifications for those who sell to the public....not to mention the way we handle our backyard systems. UV could possibly be used to kill any introduced E.coli or Salmonella from birds, unwashed hands, pets, etc. and keep algae with toxins from growing in the system.</p>
<p>Has anyone found any solid references about the use of UV in hydroponics or aquaculture that we could draw from?

Iron does precipitate out out water after ruining through uv. But uv helps with liguifing and converting waist. The water is rejuvenated so long as there are minerals. There was very little cases where uv did damage.

<p>I have concluded that UVs can damage a Aquaponics system, and their use should be on a temporary basis. </p>
<p>Good Things about UVs</p>
<p>1)UVs can Kill Green Water Algae which can make the tank more attractive. Elimination of the Green Water Algae that consumes nutrients could be beneficial. </p>

<p>2)UVs can help correct ORP problems. A well designed system should not have ORP problems, but if a problem did arise that caused a drastic fall in ORP a controller could turn on a UV until the problem could be resolved.</p>
<p>3)UVs can Aid in disease protection. If fish are sick a UV can help but should be used on a temporary basis. Also the UV could be used when introducing new fish into the system. The new fish and the water that they are in could contain diseases that would most likely be eliminated with the temporary use of a UV.</p>
<p>Hear is one that i just made up.</p>
<p>4)UVs Could be used to clear water before adding new minerals. Because UVs can precipitate minerals out of solution they could be used like a restart button. For example.... if your systems water had become unbalanced other time and possibly had to much of something you could run the UV until the water cleared. After the water cleared you could add minerals like Glacial Rock Dust. </p>
<p></p>
<p>Harms Of A UV</p>
<p>1) the continual use of a UV can cause serious mineral deficiencies.</p>
<p>2) Improper sizing of a UV can cause more harm than good. A UV that is to small might not treat the water properly wile a UV that is to large could also cause problems </p>

<p>The water in the test above was exposed to UV continuously for 10 days... where the water in your tank passes through the UV sterilizer for a few seconds out of every hour. So, over the course of 1,000 days you might have to add a little more chelated than normal?</p>

<p>Also, they didn't "do" anything with the precipitate to see whether or not it would dissolve back into the system when when the iron level in the water dropped. Precipitates are not necessarily "permanent" after they form.</p>
<p>And, according to Technaflora Plant Products, UV light can convert iron into the form that's actually usable by the plants:</p>
<blockquote><p><span>In terms of using a UV light sterilizer, UV lights can reduce the Fe+++ form of iron (not absorbed by plants) to the Fe++ form (absorbable by plants). Therefore a portion of the Fe++ might precipitate in the solution although this amount will be very minute when compared to the total iron concentration of the solution. Further, this process happens gradually over time and with repeated exposure; and as such should not create any adverse effects on your plants given that the solution already compensates for some iron loss and your reservoir is changed on a regular basis. </span></p>
