I can't grow chaeto for the life of me, not with the best grow bulbs, not with an arid system. nothing.... has anybody tried using Ulva macroalgea as a nutrient export exclusively in place of chaeto? pros??? cons??? does it go A sexual like Calupra? does it grow fast enough to even be a contender?? can it be grown in mass??? will it spread into the display and be a nuisance??? I do not have any tangs... don't want any either....
