Sorry for the abbreviated first post. Our 2 year old needed some help getting back to sleep.
Some more details about the tank. It's a standard WaterBox 6025. Right now, it's just low tech, with the single FX6 providing filtration. I'll be swapping the FX4 from my 75g soon, with my Cerges reactor and UV filter.
WB 6025: 60.5"x25.3x21.7", 143.8 gallons
Filtration: 1x Fluval FX6
Heater: Helios PTC at 76 degrees (in-line heater unit made from 2" PVC and cable glands)
Soil: 18L of UNS ControSoiL + a mix of sand
Now the theme of the tank. My wife and I live near and got married close to a river here in CO. Even though it appears to maintain the same course, if you know it well enough you can see the changes from year to year; a bank is more eroded here, a boulder shifts there, a tree falls into the river in another location. It's constantly changing course. The basic idea for the design in this tank was that of a Brazilian highlands river that had shifted course and overtaken a dead tree stump and rocks that had accumulated around it after most of the soil had been stripped away during high water events. The UNS ControSoil is mixed in between the many rocks and held in place with HDPE paver grids that also serve to protect the glass from the rocks.
All of the plants are typical SA/Amazonian varieties; Echinodorus bleheri, Echinodorus cordifolius, Echinodorus quadricostatus, Hellanthium tenellum, Hydrocotyle leuocephala, etc. Some of them are having a tough time transitioning from emersed to submerged life and a good pruning session will be in order soon. All of the plants have submerged leaves growing in, so the plants will survive, but the tank will look a bit sparse in areas, for a bit. Also, we've had an unpredictable winter here and buying mail order plants at this time of year is a risky proposition. I have some pretty big E. cordifolius growing in my 75g that will get a short bath in an H2O2/Excel solution, then come over to the new 6025.
