<p>Hi Len,</p>
<p>If you're going to go that far, then it should be a good idea to clean the system and start a cycling again. It will be added work but at least you'll be more on the safe side.</p>

<p>Can you find the manufacturer of the liner and do some inquirers on this particular product ? An MSDS would shed some light. From there you will have a better idea of what you'll need to do with the rest of the system.</p>

With this info, it makes good sense to change the liner to something like the duraSkrim product. No metal parts in the system. Maybe instead of a small raft system I will use towers. Totally avoid the whole problem. Thanks for the info. If in fact there is some chemical leaching this early on, I wonder if it has contaminated the grow media and this needs complete changing as well. This could be very expensive to fix; a completely new system

<p>Ok then, nitrites seem kosher. <img src="http://www.bkserv.net/images/Smile.gif"></img> Any metal valves or pipes in the system? Copper, zinc (anything galvanized), brass? </p>
<p>Now, everyone needs to do their own thinking/research and make their own decisions on the PVC liner front...but you really need to know that there is a HUGE difference in rigid PVC (like your pipes) and flexible PVC (like your liner).</p>

<p>Now, everyone needs to do their own thinking/research and make their own decisions on the PVC liner front...but you really need to know that there is a HUGE difference in rigid PVC (like your pipes) and flexible PVC (like your liner).</p>
<p>In order to make PVC pliable and soft, a "chemical softener" must be added. These substances are called plasticizers. The most common plasticizers added to PVC in the United States have been banned in many other countries and continents. These plasticizers are called pthalates (BPA being one of the most problematic and unfortunately among the cheapest for industry to use...but there are others...DEHP, BBzP, DBP and a few more cheapies). These pthalates are quite toxic and have been linked to much nasty stuff...birth defects, various cancers, all sorts of freaky stuff...they fall into a category of toxins called hormone disrupters, which is a <em>particularly</em> nasty type of toxic...</p>
<p>To gist of the problem when using these products lies in that, on an atomic or molecular level, there does not exist (nor can there because of the nature of the substance) a covalent bond between the PVC and the pthalate plasticizer. So the chemical bond is a <em>very weak </em>one. Since it's so weak, the pthalate leaches out from the PVC and makes it's way through various vectors, into our blood streams, biological systems, AP water etc...Vinyl (which is what most folks call pliable PVC, is a horrible material...both because of it's crappy mechanical properties, and because of all the toxicity issues which surround it. But that is why it is so inexpensive...It's 'cheap' all around)...</p>
<p>Now, I am <em>not</em> saying (at all) that, that is what is killing your fish...might be, might not be...but that's not the point...</p>
<p>Just giving you a heads up so that if you wish, you can look into the matter yourself and make an informed decision about whether you wish to keep that liner in a re-circulating food production system for you and your Family. Since now that you're aware of the difference between rigid PVC and flexible PVC, you may wish to fork over the couple bucks for a good quality plastic (non-vinyl) liner like LDPE (low density polyethylene) such as the one 20mil liner that DuraSkrim makes. (I see that they've recently started marketing it as "Aquaponics Liner"...good marketing move on their part)...</p> Hi Vlad, The nitrite level w…tag:aquaponicgardening.ning.com,2013-05-15:4778851:Comment:4756512013-05-15T21:03:39.125Zlen piercehttps://aquaponicgardening.ning.com/profile/lenpierce
<p>Hi Vlad, The nitrite level was very low and not measurable using the water tester kit. The color was at the 0ppm level. I thought there would always be some nitrites, but after they peaked, they dropped to 0 while the nitrates continued to climb to around 40ppm. Through out all this, my nitrates have continued to stay at 40ppm or higher. I almost makes me think the bacteria in the grow media didn't die like the fish.
