cheers Si, its needing trimming weekly though! I would recommend using some Purigen (seachem) in your filter, Si. I started to use it as AC, claimed his water clarity was great with it. It looked clear enough to me last time i saw his tank...so i bought some to see what he was on about. Honestly, it looks as though i haven't got water in my tank now! Well worth the money for he water clarity alone.
o thats really cool. Did you have to tie the riccia fluitans down to small stones or are you able to just plant it in small sections equally spaced on the floor. i want to cover the hole front of my tank so 80cm by around 20-30cm in places
