[bharada]

I have a small patch of it planted in my 125g. Substrate is a mixture of coarse quartz sand (3-4mm grains) and Shultz APS. I did trim it to under 1/2" when I planted it, but after 3 months it's has done almost nothing...it hasn't melted, but runners are few and far between. And it does have a tendency to collect hair algae which I dutifully comb out weekly.
