I've been working on this for a while, and I have to say thanks to everyone on this forum for lots of helpful info that they have posted in regards to their tanks. I hope you all realize that there are a lot of people out there that get great information from your posts. Hopefully some people will get some good information from mine.
I've just received the tank. It's a large 40" pentagon but fairly shallow at 18". It's open on all sides so I had a tough time designing a scape, but finally decided to keep mostly foreground/groundcover plants. Probably Marsilea minuta and Hemianthus callitrichoides. I might have a few midground type plants in the back. Maybe some glosso or dwarf cardinal plant. There will be some floaters in the back also to provide some shaded area and more hiding places.
Hi-tech ... because I'm that kind of guy.
Tank size: about 100 gallons after subtracting hardscape, substrate.
Light: 496 watts lighting: 400 watt dimmable 10K metal halide and 96 watts 6500K T5.
EI fertilization schedule: automated with peristaltic pumps and Aquacontroller.
Water changes: automated with solenoids and Aquacontroller, probably 10% daily.
Water parameters: straight RO for now, because my GH is 20 and KH is 16.
Over the last day I've created a slate barrier wall or retaining wall and poured some shallow 1" ADA Sarawak sand on one side and ADA Amazonia on the other. There's a cool cave that's built in to one side of the slate wall. There are lots of little crevices so maybe any fry might have a chance to hide before getting eaten.
I've got a mini "Ode to Iwagumi" on the right side and an old curved piece of Mopani functioning as a kind of retaining wall for the slope. And for something to chew on for the plecostomus. I know wood and rock are tough to combine, but I'd like to give this a shot. The rock is petrified wood anyways, so it is kinda wood
Pics to come ...
