Rolling Cheato

[Willow]

my sump is basically a big fuge, i have a couple of different macros growing in there. they grow well and i have to thin them out all the time, my nitrates are zero so they must be working. the other day rob gave me a hunk of cheato and i just chucked it in there with everything else. i was looking at RC and people are going on about getting their cheato to roll in the sump. is it necessary for it to roll to be effective and grow? i just assumed that it would grow along with everything else in there.
