Will you post params please? Last time I took someone's word on normal params their Alk was WAY off. I do believe you though, 5 years in the hobby!

You dipped the coral you were most concerned about? Found no pest? No bugs crawling on them?

Is this affecting only acros/stags or are other coral showing signs of distress?

If not a pest, must be water related. How and what are you dosing? Perhaps a Triton test is in order?

Doesnt really look like AEFW bites looks kind of like stn. Did you make any changes to the system recently? Change the lighting or flow add any new equip?

thankkkku allll.
im sorry to respond late ......
i had a low kh poblem for the past few mounths..... and someone turend off chiller last month and corals had a shock..........
but the problem is in some parts and its confuse me.....
the mother colony is doing well in its left.... but we have this problem in right side ( but all of it is in shock...)
it is not AEFW .... its like there is something eats this one....
we have microscop in here and we saw the coral in the morning.....
in those parts ( white streamy part in middle) ive seen very little eggs i think.... veryy little......

I can't say it's not hydroids, but I think there's something else going on. SPS typically doesn't react like that to even hydroids.

Low Alk means what? For how long? What is it now?

How hot did tank water get?

 

[Benyamin_Givi]

it seems they are something like AEFW but very smaller...... we advance to cure them.... hope they going well.... thank u all for your time
