Thanks for the comments, guys! 😀 I find working on this small scale suits me as I always get new ideas and breaking down your tank every 2 weeks is a bit impractical.
Yes, Neil the light is from John Lewis, I don't think it does any actual photosynthesis. I keep pestering the guys at TGM to import the ADA lights specifically designed for these scapes. (you can see some in the tours of his gallery on youtube). Desk lamps are Ok but can easily burn emergent plants I've found. The container the VF scape is in is quite cool it's acrylic but looks like glass (also from JL)
I'm really fond of the bowl, always somthing new poking out of the riccia. I got the idea to try riccia from frog tanks but it seems to be a good planting medium for other species, like a big sponge. I periodically squirt some TPN in. The bowl is 20 cm diameter.
Cheers, T
