So we lost water and obviously nutrients etc. Added drama was the shade cloth split in the wind.
Being away and leaving it all to Wanna seems a bit unfair but what can I do!!! She did a great gob and got it all sorted. Needless to say it has had some effect on the fish. Fresh water etc. We have also continued and had a few of the small fish die. Roughly one a day this last week. The bigger tank is fine and they have got back into the habit of jumping up for food. Good sign. However given the mortality rate for the smaller ones and looking at the waste coming from the tank (see below) I suspect we are giving them to much food. Wanna (again down to her) has reduced the feed on the small ones by 50% yesterday and the waste/return looked good with little to nothing rising to the surface in the big tank. So all is beginning to look positive.
We're (royal we) have also planted "Morning Glory', an easy fast growing hardy plant with does take up a lot of nutrient but gets everything up and underway in what I hope will from now on be a continuous manner.
