Day 15 no pic as there has been no real change a tiny bit of cyno and a tiny bit of diatoms but nothing trublesum mainly to the tank being to clean for a week and rebalacing itself since the bryopisis is no longer using up anything the trouble spots are still there but not growing so I can say with 100 percent certainty that this stuff only works with light and the higher intensity it is the faster it works only other this is noticed is overall coral health has improved (they are getting more food since the bropsis is gone) and the coraline has really taken off as in in the last week its went from about 30 percent coverage to 90 percent coverage every rock in the last week that was white or green has now turned purple not bright yet but a light hue with dark spots everywhere
