Aquaponics-EPIC FAIL!

Our second full year in the greenhouse with the aquaponics systems has been wrought with a few mishaps and mistakes. Nothing major-lines burst, junctions break, heater burnt out, air pump stopped-but today I woke up to an entire tank of dead tilapia fish!

It happened in my constant height tank, which was the first of the type that I had built. I had cleaned out the 3 stage filter last week during our warm weather snap because the water was starting to turn a little too brown. I checked the ammonia level, which was high but thought it would go down after I cleaned the filter.

I never cleaned out the grow bed. Honestly it never really dawned on me as I had the 3-stage filter and the gutter garden circulating water for filtration in this tank, but I did not grow anything in this grow bed over the winter.

This morning, after removing the fish, I took off my 3-stage filter and it was already full of sediment. So I looked under my grow platform and it was 1-2″ deep in solid fish waste! The ammonia level was through the roof, so no doubt why all the fish died.

Needless to say I am pumping all the water out of the tank and cleaning the grow bed so I can start the system fresh with new fish. We had been talking about changing this particular tank to a cold water fish, so we would have 1 tank that did not need heated. I guess that decision is now made.

Unfortunately, I was planning a neighborhood fish fry next weekend to utilize the fish from this tank. Most were 14-18″ long and 5-6#-perfect for a big fish fry! I guess the fish fry will be postponed for a while!

As with everything, there is a learning curve, one just hopes for no sharp turns like this! But with this epic fail, I have a chance to start fresh and utilize my new found knowledge to become even better with my aquaponic gardening.
