Zoa dying or not ?!?

[mrvincent]

This little part of my zoa is not opening, and is whiter than the other parts... Some parts don't close at night, and some don't open at days...

I reduced my light from 75% to 50%, everything look bleaching in my tank except my frogspawn... I turned the zoa frag, so the healthy parts are more near from the light, and the no healty part is under, so it recieve less light, but I don't know what this will do, I'm new to this hobby, and It cost me 25$ for that frag.

I know it's no a beautifull frag, but I wish the rock will be covered

You could try a dip in ro

How to do this, and what benefits will it do ? I dipped it in Seachem Reef Dip with aquarium water when I bought it there's two weeks. Found few aptesias on this frag that I immediatly killed with aptesia-x, but I think it's too late and my tank may be contaminated ...

So, what's scientific reason to RODI dip it ?

 

[mrvincent]

I read some about freshwater dipping. This is to remove hitchhickers/malware/trojans?

Can I take RODI water, put some buffer to have a 8.0-8.4 PH ?

It looks to me like you have a sponge growing in between the polyps and choking them. No dip is going to correct that. I would take a small tool and scrape out between the polyps and see if that does the trick.

If you already used reef dip I doubt freshwater would help, but you could give it a try. Just bring ro up to temp then dip frag and swirl and agitate for a few minutes then return to display.

Then I'll wait a little bit more, and I'll give you news in 1 week, just to see if what I've done now is ok... If not I'll probably try the FW dip.
