Hello - I got some frags at a swap and a they have bubble algae on them. I take them out of the tank and remove it and it just grows back. They have been in the tank for two months / still on frag rack, what should I do? I don't see an easy way to take the zoas off the plug...Use a hack saw and cut off half? I promise to wear protective gear due to toxins! Thank you all for your time
