I bought a frag of my lfs it had a bit of algae hair on the plug . I thought just switch it to a new plug and it would be good . I switched it and the algae was gone a week later I start to see algae on I tried to take but I didn't want to put stress on the zoa . Now it go to the point the zoas dont wanna open up . Is there any dip that will kill the algae ? I tried iodine dip and that didn't work ? Can anybody share there experience with algae hair on frags .
