Clean algae from zoa frag

[lastlight]

I did the 5 min dips on two pieces. Both opened up a few hours after but the algae still appeared healthy. Was lots of fizzing in the dip though. 24 hrs later the algae on one is 100% gone and the broader leafy bits on the other appear semi transparent/dead so will wait another day before I decide to double dip. Will be dipping a larger third colony as well now seems to work great.

With one colony retracted i found a small aiptasia. Dip did nothing to it of course.
