This is my experience that I want to share, oh, hi to everyone. I had my system (1000ltre fish tank, three growbeds an IBC cut in half and a tin bath) I was putting one cap of seasol each day and I was dutifully checking PH, Nitrate, Nitrite and Ammonia daily. I had a PH of 7. and the rest were 0, and the veggies were slowly starting to grow. Great you may say. Great I said. Then I thought "Budg old mate (I always talk to myself, being old and patially mad) Budg, before you buy the 100 fingerlings that are part of the plan,why not trial the system with some good old cheap goldfish" so, off I went to the local aquarium shop and bought 10 bronzed goldfish, and, following the directions in the vid, I put them in the tank.Im off and running, yahoo. All of a sudden one of my water pipes to one grow bed stopped flowing and then the other one did the same. I had to take the pipes apart and found bits of two of the fish inside the pipes. I realised that I didnt put a filter or cover over the ends of the pipes that extend down to the bottom of my IBC fishtank. So I had to take both of these out and I bought two caps that I drilled holes in. I was away for two hours. When I came back to the tank to put the pipes back in there were parts of seven of the eight remaining fish floating and dead. I had left the system running and the fish had all committed hurricurri.
The moral of my story is, Do it right the first time, dont rush to have a system up and running, R.I.P goldfish and dont give up.
Regards to all
