Accidentally lost URL for Aquaponics article.

Damn it I was looking at an article on basic hydroponics but accidentally closed it before saving it, and it was a British article as well. If you know of it please tell me.
From what I read it was two homemade aquaria on a Dexion angle iron frame, the aquaria were 18 inches high, 8ft long and (I think) the bottom tank was 24 inches wide but the top (planted one) was 18 inches wide ( could have been the other way round).
A solar powered pump was mentioned but I didn’t get far enough into the article to see about how they maintained the aerobic bacteria in the filter bed over night.
The top tank used water hyacinth and duckweed as the filter media to absorb the nitrates/ nitrites etc. and I think the chap said he had the option of growing cyprinids (carp) or Tilapia.
If you see this article can you post a link to it for me please.
