the pond has been going for 2 months now. The fish are fat and happy, the strawberries small and somehow not so happy. I suppose there are not enough nutrients left for them after the water plants and the algae have had their share. Especially the algae is a bit of a problem, I have already put up an extra sun sail to shade it more but of course they are still thriving. Still it is pretty and will be expanded to two columns of hydroculture next year.
