As the title stated, I recently changed around my 75 gallon grow-out aquarium to feature a hardscape that was modeled after Aquarium Design Group (ADG) and the Iwagumi style. This hardscape was put together using whatever rocks and driftwood that I had on hand, so it's not exactly what I was going for, but I think that it looks pretty good when my limited materials are taken into consideration.
I'm not exactly sure what kind of rock the rock is, but I think that it might be sandstone. The driftwood is crab apple (Malus spp.) which is supposed to be fish-safe and hold up pretty well underwater. The wood was stripped of its bark and sanded before I prepared it (soaked, boiled, etc.), but it has yet to become fully waterlogged and is held down the the rock.
I'm considering adding plants, but I want it to be low maintenance, so I'm not 100% sure about doing that. I was also thinking adding some more rock once I find some good smaller pieces. I'm not sure if I want to keep this kind of driftwood or not, but I do want to get a branch/root type piece to add to the mix and maybe also add some more stick type pieces. I also want to get better lighting since the current standard fluorescent lighting gives photographs of the aquarium a yellow tint. Eventually, I'm going to replace the current stock with a small shoal of piranhas, so I'm hoping to make the hardscape accentuate both the current inhabitants as well as the future ones.
Any other suggestions?
