Last post was 13th Dec last year. Seems ages ago. Been busy with work and visiting other aquaponics systems. Notably my mate Rene's. No photos from him.
Also visited "ponic wars" on www.youtubecom . He seems busy with all sorts of stuff.
For me, and why I'm posting this is to let you know I'm moving house in a few months. Found a place with about 50 square meters of flat concrete roof and some shade area suitable for fish tanks. So things will starting to happen again soon.
Cheers for now and happy growing.
