Interesting. How much light did you have?

About 2w/gallon reg FL's.

I am trying to grow a small lawn of hairgrass and glosso in my high-tech tank
(100% Onyx Sand). The glosso is growing like a weed, but the hairgrass is
growing very slowly.

Once it gets going it'll do fine.

Maybe I should trying moving the hairgrass to my
low-tech, Flourite-substrate tank.

They should do fine in both, patience, patience.
