I just finished setting up another display/sell tank at the store.
It is a 33g 24lx18x18 Mr Aqua Rimless.
Using Mr Aqua soil, and co2. Eheim 3 filter
The purpose of this tank is to accomplish the following:
Demonstrate a CO2 system to potential customers
Show off what a difference has a substrate vs gravel in planted tanks
Proper lighting (35-40 mol at substrate)
Landscape in a way to house fancy plecos (hence the embedded driftwood)
Landscape it in a way to merchandise fish easily
