My aquarium seems to be working. Did a quick test and my CO2 levels are the lowest category possible, but most plants I have should not require it. Currently I have a very simple setup, at least compared to some of the mindboggling creations over at /r/aquascaping that I gawk at. But my setup is working, and my two Amano shrimp seem content. Want to keep this tank for a bit before I start thinking about something bigger/better - I first need to make more mistakes before I can do advanced stuff, I think. We visited the Waterloopbos the other day! Did a double-date thing with an ex-coworker of mine. Had a great afternoon of walking around, looking at the 30+ now-ruined flow dynamics experiments and birds and plants that my friend and his gf were good at identifying. The forest is (by Dutch standards) actually lively and diverse in nature due to most of it being underwater or near water.
