<p>Hi Jeremiah,</p>
<p>I can't say I agree with your statement. I have run <a href="http://aquaponicssystemsolutions.com" target="_blank">100 gallon systems</a> and have no problems. Provided you have at least a 12" deep media growbed and maintaining quality and consistent amount of fish feed.</p>

<p>Originally I had 800 tilapia fry in a 45 gallon aquarium ( thought there only about 300 until I counted) They grew there to about an inch before I moved them to an IBC. I had a continuous ammonia problem no matter how little I fed them even with constant water changes but none of them died to my knowledge. Right now I have 14 3-4" tilapia in that tank and the PH hovers around 4 and the ammonia/ammonium is 2-4, deadly in everyone's book. Still no losses. Yesterday I finally put a teaspoon of…</p>

I had a continuous ammonia problem no matter how little I fed them even with constant water changes but none of them died to my knowledge. Right now I have 14 3-4" tilapia in that tank and the PH hovers around 4 and the ammonia/ammonium is 2-4, deadly in everyone's book. Still no losses. Yesterday I finally put a teaspoon of Calcium Carbonate in the tank and today the pH is 6.9 and ammonia is .5. Hopefully those #s will hold.</p>
<p>Short story long, over the past 6 months I've done all the wrong things with no fish losses (knock on wood) so I have to believe something drastic had to happen to your fish. Oxygen depletion or as Jonathan stated a sudden build up of ammonia. The only thing I can add is that I believe my fish survived the high ammonia readings because of the extremely low pH. Below 7ish pH ammonia becomes ammonium and fish can process it without damage. Try to add a buffer of some kind to slow rapid changes to your water readings. I'll let you know how my addition works.</p> 100 fish in 15 gallons is pre…tag:aquaponicgardening.ning.com,2014-06-29:4778851:Comment:5692332014-06-29T05:36:39.491ZJonathan Kadish NYC AA Chairhttps://aquaponicgardening.ning.com/profile/JonathanKadish
<p>100 fish in 15 gallons is pretty dense stocking. Fish excrete ammonia from their gills regardless of being fed and ammonia is more toxic at higher temperatures and higher PH. Even tiny amounts of ammonia can be toxic in certain conditions. Perhaps you were in the red zone with a slightly elevated PH and it got warm in the room. 15 Gallons will heat up much faster than 450 gallons.…</p>

<p>You know, the thing this doesn't explain is what happened with my 15 gallon system. I had 100 tilapia fry (2" or so). The water chemistry was pretty stable. I had a small amount of ammonia, and nitrates but not much. However, when I was gone overnight (i.e. didn't add any feed) one night, every single one of them died.

<p>We're all amateur experts LOL. Something has to change the water. The water doesn't just change on it's own. The biggest variable I think are the fish. How much do they weigh, how much do they eat, how much do they poop? Everything else changes based on the fish. I was watching a Bright Agrotech video recently and Nate said "it's much easier to grow vegetables in hydroponics than aquaponics because of the fish variable because everything has to be worked around the fish health".</p>
