What is the lighter stem stand in the center? What kind of substrate did you use?
(aka: "golden nesaea") still slowly transforming from its emersed form. Moved some Limnophila aromatica
occupying that spot into another set-up.
Tank substrate is standard inert black gravel. Plant substrate is loam consisting of sand, silt, clay & humus in different proportions (about an inch deep); capped with black sand (about 1 1/2" deep).
The 'ole' standard (black frame) 10's are a lot of fun to play around with, and they definitely do not break the bank.
