I've got a lovely crop of purple corraline on my glass, PH
's, pipes, snails, hell - even the drain pipe in the sump from the tank (fuge lit inverse photo-period from main tank). But most of the LR
is still ... just bare LR
. I can see a few spots of the stuff in a couple of the places but you have to look hard for it. When I scrape off the glass there's mountains of the stuff in the water column for a few hours and yet still no 'taking' on the rock.
