Hi guys, 
Been following the glosso thread for quite a bit now. Well IMHO, glossos
don't really need <any> kind of special substrate to thrive (thrive, not
survive). I have been growing glossos very successfully in my 4-footer that
has absolutely no substrate additive. Just plain washed gravel! I have
noticed some of my fellow Singapore aquarists glossos too. And I've come to
the conclusion that all glossos really need is very, very strong light and
lotsa CO2. I once was fortunate enough to speak to one of the top
horticulturists (I hope I have the designation right) at Oriental Aquarium.
He told me that glossos need soft water to survive! Interesting. I do
believe however, that glossos do better in finer gravel than coarser gravel.
I am now trying out a small cube tank with glosso grown on fine lawn sand.
To keep them really low though (those in my 4-footer literally hug the
substrate, with no stem showing at all!) I'll be using very strong lighting,
with a waterfall system to try and cool things down to at least 28 degrees
C. Oh yes, they do do better in water that is cooler. 

Here's my suggestion: Why not try a tank solely with glossos. Use fine sand.
Have very, very strong lighting and cooler (25 degrees or so) water and just
add a regular dose of liquid fertiliser (well that's all I use :-) It's
truly a beautful plant, as one look at Amano's tanks will attest to) and
deserves a second chance :-) Give it a try man:-)

I would love to grow lilaepsis too, but somehow, I have never succeeded.
