Thanks all for the kind comments! HappyCamper, it'd be nice to have a beer session with you, but ain't you in Africa?
The hobby may seems to be growing, however, the local planted tank industry seems to be shrinking quickly at the same time.
Rand, that last tank is actually an outdoor pond, with cross sectional view. There are natural sunlight, but partially shaded by the trees around. I have a goal-post structure made to support 10 x MH, if you can sport them.
Right now, we are building 2 similar, but bigger tanks. Will post some progress photos as we go along!
