Dreaming of another (grow) bed...

We're in the process of producing a WApU manual and it gave me the opportunity to draw WApU Davis with an additional growbed - I just need to find a + manifold for the 1/2" pipe!

This would get us a bit closer to the proper ratio of tank to grow bed volume (1:1) and would take advantage of the high nitrate levels we have in our tank. Don't worry - its quite stable and the fish are very happy.
