<p>Good Luck.</p>
<p></p>
<p>I would say inoculate both the bio-filter bacteria and the Actinovate about the same time after you get it all cleaned up again. But that is purely a guess on my part.<a style="cursor: pointer;"><img src="http://www.bkserv.net/images/Smile.gif"/></a></p>

<p>Another source of the infection might be your seed starting media, if you use loose peat to mix up your germination mix, you may be bringing in pythium.</p>

<p> Hello Vlad... thank you for your input and thoughts.</p>
<p>You have certainly pointed out I think the one mistake that has left us back where we were... I just didn't think about it at the time since when we first fired up the system we simply let nature take it's path, we did not inoculate with anything.

<p>You have certainly pointed out I think the one mistake that has left us back where we were...

I have a feeling had we inoculated the system first with with something like Actinovate then MycoGrow we would not be where we are. What you say makes perfect sense. The question I guess is does one establish the biofilter first within the system (I have both a separate moving bed bio filter and media beds) and then inoculate?</p>
<p>This next time round we'll try this... after sterilizing, inoculate the system first with a product like Actinovate, then give the bio-filter a chance to get established with a little help from "bacteria in a bottle" and then add a good dose of MycoGrow. Then begin seeding. Thoughts?</p>
<p>I will definitely look into the crystaline forms of hydrogen peroxide, that's a great way to do the final clean up once we've removed as much of the organic materials as possible.</p>

<p>@Shaun, I'm real sorry that you have had to go through all that. Actinovate, (according to the manufacturer) should be used as an inoculant, so I'm not sure how successfully it would actually kill oospores? It seems like the thing to do would be to sterilize, <em>then inoculate</em> as you cycle your system back up. The more beneficial microbes you have colonizing niche surface environments, the better. It will give the pathogen less 'real-estate' to work with, suppressing it's proliferation.</p>
<p>But for actually killing the pathogen and hopefully it's spores, you need something of a different nature. Non-biological. My "chemical" of choice for laying waste to anything microbial, fungal, oomycetic... is Oxygen.</p>
<p>Sodium perborate and/or sodium percarbonate are both solid crystalline/powder forms of hydrogen peroxide (H2O2). It can be stored much, much longer (and it takes up much less space) than liquid H2O2... and you can mix up the desired strength yourself according to your needs. It is an awesome and powerful sterilizing and cleaning tool. The oxygen released when it comes into contact with water will 'fry' any living microbes present in the column. It quickly degrades into mostly O2, and water molecules...and an insignificant amount of carbonate.</p>
<p>After sterilizing a system with anything, the second step is to inoculate it with beneficials. This step is often over looked, which is bad. A fresh sterile system is a heaven sent playground for aggressive and persistent pathogens to colonize.</p>
<p>Actinovate (streptomyces lydicus strain WYEC 108) doesn't appear to have any effect on freshwater invertebrates or fish. It appears to be non-toxic, non-allergenic and non-pathogenic to our aquatic friends (or any other non-target species).</p>
<p>I'm no 'authority' or 'expert' or anything, but if I were having problems and if that product were available here, I'd have no qualms about using it in a system from which I harvested and ate fish from.</p>

We have a native pepper that grows well because it is drought tollerant. It is called Chili Teppin, Chili Pequine and Texas Bird Pepper. It is tiny, about the size of a tic tac, but comes with a lot of flavor and packs a punch with capsium. Very tollerant to any kind of fungus and insect. I have a few plants that get up to 6 feet tall during the growing season. They are perrinials and mine have survived temperatures of 18 degrees F. I just cut them back every spring and they grow back. I have tried them in h.p. and a.p. and they don't like all the water. I can take a bag of all the different kinds of peppers i grow to work and share with my fellow workers that are mostly from a country south of our border and they will eat the Chili Pequines first and want more.</p>

<p>How safe is Actinovate for the fish... and at what dose/100gal of AP system water? Does one need to apply several doses in succession? <br/><br/>From my understanding it won't take out your bio-filter as it can work with the bacteria, however, more importantly is what it does to the fish, both short term and long term... especially for those of us that eat the fish.<br/><br/>Does Actinovate destroy Pythium + oospores within the system or does it simply supress it, so that should an ideal situation arise, it would flare up again?</p>
<p>Plants already infected... do they recover 99-100%?</p>
<p>We're stuck with trying to deal with Pythium (must have come from the one and only time we bought dwarf fruit trees from a supplier and put them into the system, we always otherwise grow from seed). In Jan we completely sterilized the system as best we could and began life over again in Feb. Spores must have been on surfaces we could not easily get to, really hard to say. We used pool chlorine in essence to wipe out the entire system, maintaining a level above 5ppm, as it does break down with the presence of organic matter.</p>
<p>We just sent in plants for analysis since it was clear something was up... and yes, the problem is still there.</p>

<p>im a huge fan of Actinovate and Actinoiron</p>
<p>the actinovate covers a wide range of issues and offers other bacterial benefits.</p>
<p> </p>
<p>Im in the "never heard of pythium in ap" group</p>
<p>we recently heard about "Root Mites"... they say that many rot and root issues are misdiagnosed root mite damage</p>
<p> </p>
<p>i sure have seen every other rot, bug, and mite problem there is.. in just about every ap system.</p>
<p>have you had any issue in the larger system?</p>

<p>Ok, for what it's worth, one of the two plants in my little PL lighting-mineral salts system was spared. (Originally there were four). It was also the least affected at the time of the pH shock therapy commenced. As you can see from the photo it's leaning quite a bit. It leans toward the side most effected by the Pythium where the roots and lower stem was turned to brown mush by that blasted parasitic oomycete.

<p>Ok, for what it's worth, one of the two plants in my little PL lighting-mineral salts system was spared. (Originally there were four). It was also the least affected at the time of the pH shock therapy commenced. As you can see from the photo it's leaning quite a bit. It leans toward the side most effected by the Pythium where the roots and lower stem was turned to brown mush by that blasted parasitic oomycete. I have no way of really knowing whether it was the pH treatments, or not that stopped the spread, but I kept the pH in the reservoir at pH 7.6 to 8.3 for a week and sprayed the roots and affected areas with pH water 9 (wood ash KOH). My Potassium BiCarb came in yesterday, so I made the switch to it, last night. The leaves slowly came back and are regaining a their turgidity and are losing that 'matte' look. </p>
<p>I foliar fed all nutrients and 2 days ago dropped the pH to something a bit more in line with normality (about 6.2). I'm more inclined to think that the water change (less salts) and the lower temps I've been keeping had a lot to do with the fact this plant pulled through (so far). And as with most any problems of any type...the sooner you catch it, the better your chances of beating it. (Again though, I do not know if it was the pH thing that helped, or for that matter, if I'm even totally out of the woods yet).</p>
<p>Everything in the dual root-zone organic-hydro system is thriving ridiculously with no water changes yet. </p>
