My zoas arent opening fully again due to a green algae around the base, should i consider dipping them in h202 again or lugols.

You can used targeted applications of H202 for the HA, manual removal in/out of tank, or introduce animals that might help reduce GHA while in the tank- with the CUC method, most animals will avoid longer strands of GHA, so it's helpful to manually remove the large masses and let them keep up the maintenance afterwards.
