Re: hard headed... oops, water

I live in what may be intermediate water between SF distilled equivalent and
Tom's current liquid rock (and I presume that of the anonymous poster,

I have about 200 ppm as CaCO3 equiv. and 270-300 ppm tds.

Tom's statement may be quite accurate, but leaves out a few vital details. I
have never kept Gloss. alive in my tanks, while it seems nearly
indestructible in really soft water. The key, though, was my low-light,
low-nutrient, low-tech environments.

If, and only if, Glossistigma is getting high light and full nutrients does
it seem to survive in harder water. I'll be trying some again, soon, now
that I'm injecting CO2 again, feeding and zinging up my lights a lot. I have
very little doubt that it will grow in my "hard" water if I do that.

I can't grow Cabomba worth a darn, either, but I know that's because it
would prefer to have the light from a nearby supernova to do really well.
Mere direct sunlight isn't adequate. :^)
