...well, I shouldn't say "all native" because the tank has a few exotic species as well. But, all plants in this tank were collected from local lakes, so they are a part of the Wisconsin ecosystem now (like it or not).
This tank is designed as a learning tool for students and the public. I work at the UW Center for Limnology http://limnology.wisc.edu/
, and this tank is one of the first things people see when they enter the building. It is placed in the wall between the entrance hallway and a conference room.
The tank has traditionally been a fish display, usually holding the "standard" fish species of Wisconsin (bass, bluegill, perch, bullheads). I have been wanting to convert it to a planted tank for some time, and with a lot of help from UW Professor John Glaeser http://www.aquariumgardeners.org/Default.asp
, the tank is finally on its way.
I collected all the plants. John masterminded the aquascape.
The tank does have CO2 injection. The line simply goes into the air feed of a maxijet 600. This is not the most efficient way of injecting the gas, but we have a 100+ pound tank, so at the current bubble rate, we will run out of gas right around the time of my retirement. This huge CO2 tank is actually on a lower level of the building. The line (Tygon) runs up through the floor.
The substrate was very inexpensive. John buys it in bulk from a local gravel company. It has a layer of soil underneath.
Current tank specs are:
96w PC lighting
No filter - Maxijet 600 for water movement and CO2 injection
pH = 7.0-7.1
GH = 15
KH = 10
NO3, PO4, Iron, and Micros were dosed to optimal levels when plants started showing signs of stress.
1. Coontail - Ceratophyllum demersum
2. Fern-leaf pondweed - Potamogeton robbinsii
3. Chara sp.
4. Sago Pondweed - Potamogeton pectinatus
5. Eurasian Watermilfoil - Myriophyllum spicatum (exotic)
6. Vallisneria Americana
7. Illinois Pondweed - Potamogeton illinoisensis
8. Elodea - Elodea canadensis
Unseen - Curled Pondweed - Potomageton crispus (exotic)
Unseen - Duckweed - Lemna minor
