I can sure see the pearling coming out from my crypts and anubias (nana & barteri). I think I've read somewhere that the pearling is oxygen that cannot be diffused into the water which means that the is a 100%utilization of diffused oxygen in the water, hence the pearling released directly to the atmosphere.- But I cannot really back it up though it does make sense.... Anyway pearling is nice to watch anyway. BTW: Is it common posting in this group your planted tanks ?
