It seems that the water adjustments we made using hydrochloric acid were not that good for the fish. Even though it did bring down the pH to 7, it seems that the 400 fish we put in were not too happy with it. They started to literally rot alive. In the first 3 days we lost over 100 fish and finally changed over 75% of the water. The fish deaths have been going down, yesterday we only lost 6. Still have about 250 fish in the tank, more than enough for aquaponics to work out well!
We have our first open house this sunday at evfuture. August 15th, 4 to 6 pm.
