Help! Zoas not opening up!?

[peacemaker]

I dipped 2 zoa frags in Lugol's solution yesterday evening, and they are half opened today. I hope they are on the road to recovery. What should I do to buffer the Ph of the distilled water (for the dip) so as not to shock my corals? Do I have to dip everything in my tank to ensure that they are free from zoa eating pests? I've read that some reefers fight these things for a month or so. Makes me want to perform 100% treatment of all corals and rocks, but I fear it might be over-doing and killing what is good. Any advice?

Anyone? Also, is it ok to use Iwarna's Top Up for the dip?

I found these in my filter wool today. Had the luxury of taking pics under a microscope. These guys were the ones that jumped off my zoas when I performed the Lugol's solution dip. I was told they are copepods... can anyone comfirm? Also, will they be harmful to zoas?

I don't think they're harmful, I believe they are pods, specifically which type, I am not sure. I have a tankfully of them but they just scurry around. Some can get rather big, about 0.5cm and red in colour

Yes, got an ID on them. They are called amphipods.

Yeah.... maybe it's bcos I shocked them by placing too near the light source when i bring them back.............

Thanks for your advice.... going Auntie there later in the afternoon. get another piece to try.....

i bought my zoa one week ago, no problem..opens up whenever i switch on my lights.

And they are on the mid-level of my tank.

My zoa is size of my hand.

I think they like moderate currents and dun place them near to corals that stings.

And i feed them with phyplankton from reefmax everyday.
