Yeah, give it a week or two and I'll really have something to show you.
It is getting close to done, the HC is doing its thing and the hairgrass is sending out runners. Since adding CO2 to the tank, it seems as though things are speeding up, but it could just as easily be perception bias or things are just hitting the sweet spot anyways.
As far as the dimensions go, it really is like a much larger tank than the actual gallons. I can't say enough good things about GLA stuff, and while the silicone work is not quite as good as my ADA mini M, it is still the "coolest" tank I own and ADA does not have an equivalent size. There are a few other journals floating around with the Mr. Aqua 12 long as well, which has the same dimensions.
