Btw, if your pond is off-grid, then a small solar grid would supply the air during the days, which I assume would be enough. My deep-water tetra air pump will push water 8' down, and runs on 7.8 watts. Harbor freight has 5 watt solar panels for $20, so get 2. I think I'll try it on my little pond. The circulation will probably improve the pond health as well.

I've got an idea for improving your pond system. How about taking a 10' length of flexible drainage pipe, and securing on end to the middle of the underside of your raft, and a weight on the other end to hang it in the water column or rest it on the pond floor. Into the pipe you could run an airstone and a deep water air pump, as deep as possible for your pump/power options. The ascending bubble stream will oxygenate a huge flow of nutrient rich water off of the pond floor up to the bottom of…

Into the pipe you could run an airstone and a deep water air pump, as deep as possible for your pump/power options. The ascending bubble stream will oxygenate a huge flow of nutrient rich water off of the pond floor up to the bottom of the raft, and provide some current to the roots as well. If my recent studies are true, then the anaerobic floor of a pond is rich in nutrients including iron.

<p>Thanks for the replies, the problem is indeed a roots rot issue due to lack of oxygen. After investigating further, I realized that there is an increase in the algae build up on the net underneath the board, which is limiting the water/air flower to the roots.</p>
<p>Have changed the net since, and the new net has a bigger hole so as similar issue won't happen again. Will post up the pictures soon</p>

<p>I think pond aquaponics could be made to work, however it will have very different complexities from a normal recirculating tank type aquaponics. </p>
<p></p>
<p>Remember it is all about letting the ecosystem balance. If a pond is already in balance with it's proper amount of algae and other things, then simply adding a raft of plants doesn't work well since they need a different balance of oxygen and nutrients and if the system is already in balance, there isn't enough of those things left…</p>

<p>I tried for a year to get aquaponics to work with my koi pond with the same results you are having. Once I built a proper aquaponics system I was successful immediately. I believe that aquaponics does not work well with ponds because of the sunlight hitting the water and the anaerobic areas. Sunlight hitting the water will cause algae to bloom during the day consuming nutrients. Ultraviolet light will kill the beneficial bacteria.

<p>I tried for a year to get aquaponics to work with my koi pond with the same results you are having. Once I built a proper aquaponics system I was successful immediately. I believe that aquaponics does not work well with ponds because of the sunlight hitting the water and the anaerobic areas. Sunlight hitting the water will cause algae to bloom during the day consuming nutrients. Ultraviolet light will kill the beneficial bacteria. During the night the algae dies and begins to rot which consumes oxygen. Ponds of that size will have large anaerobic areas which will consume oxygen day and night. The more oxygen to the roots the better. Your pic shown sever root rot probably due to lack of oxygen.</p>
<p> It may be possible to try a floating wicking system. Have pots of media suspended above the water on rafts and have a wick going from the media down into the water. The wick will draw water to media and keep the roots wet as well as oxygenated.</p> Hi VincentYou mention growing…tag:aquaponicgardening.ning.com,2011-12-23:4778851:Comment:2688172011-12-23T15:01:21.652ZFrancois Lemmerhttps://aquaponicgardening.ning.com/profile/FrancoisLemmer

<p>Get an air pump and put some air stones down below your rafts. DWC (Deep Water Culture) or Raft culture always needs supplemental aeration.</p>
<p></p>
<p>Fish density, Well rule of thumb is really designed for the recirculating type of aquaponics system. It gets much trickier when you are talking about a natural pond without the recirculating aspect. In pond culture you are limited in different ways.</p>
