Disaster. That's right a disaster. I went to Laos for four days only to get back and be told by the guy looking after the system that over night (last night !!!) it, the system had somehow run nearly dry. I suspect it is the local cats playing around on the top, maybe the pipe from the pump to the reservoir had become dislodged. Can't think of anything else or any other way it could have happened. I had noticed the cats around before but though little of it. So the result of all this is that bigger Tilapia died. That's 7 of them leaving me with 4 small ones. I'm am really disappointed but am taking it as part of the learning curve. How quickly things can go wrong. One day all is good and the next?..... Well I am really down about it.
I had been so excited to get back and plant the new seedlings. Probably still can plant them and maybe just maybe it will be OK but, ...not sure on the balance of fish and veggies any more.
Must get some more fish ASAP.
Imagine if it had been a fully commercial set up. A whole crop lost.... Well I am planning this weekend to add a few more small spry and see how it all goes. Major disappointment all the same.
