I have a nice lawn off riccia growing in my tank which is lovely and healthy, but i read off peoples riccia pearling why doesnt mine, apart from that it is growing nicely.

i am running bottle off co2 which is always at its optimum level, i have fertileser substrate, under gravel heating , 5 dennerle 42 inch t8 tubes and add weekly ferts and also do a 25% water change every 2 weeks.
