Hi mrkookm,
thanks for the reply.

substrate: local river sand and fine gravel.
lighting: cool daylight (6500K) CFL (
link - not a lot of info)
lighting duration: 7 Hours @ 4.4wpg, 3 Hours @ 1.1wpg
reflector: diy. the above levels are just enough to keep glosso spreading rather than climbing.
Co2: yeast. 25-35ppm. measured by drop checker and calibrated by gasping fish (once
)
traces: garden variety trace mix (
link - pdf). see 'code' for dose.

dosing: all dosed daily.
most recent changes to dosing:
added KH2PO4
-Elodea - very slow growth increased to about an inch a week
added K2SO4
-Elodea - growth increased to 4-6 inches a week. A little pale and transparent but not badly so.
-'hairgrass' - resumed growing runners, though very slow and pale.
glosso is almost gone now, so I'm on to saving the hairgrass
