Loosing large SPS colonies

[Werbo]

Rich ... Thanks. My other 3 valida are in close proximity and are doing real good and thriving. I mean REAL good in every way (polyps, color and growth).

Just dipped a large 4+ inch multi-branched frag of the affected turaki. Nothing unusual after 10 minutes.

Been no alk swings so I am still looking for suggestions and still puzzled.

I love wrasses so I'll buy another melanarus wrasse on the weekend when I am at J&L. If they have 3-5 juv yellow coris wrasses I'll pick them up too for pest control. I've always wanted a herem so this is a good excuse.

Time to cross the fingers and hopefully Kien can throw a prayer into the prayer reactor for me!

This guys says he has an AEFW treatment if it is that. Pretty interesting thread.

Dipped frags of the affected corals and didn't see any flatworms so not gonna panic quite yet.

Gonna read that thread thou as I'm a bit out of the loop on in tank AEFW treatments.

i know u said water is stable but post ur parameters is nitrate or phosphate up at all ? Alk swings can cause this, nitrates can cause some colonies to be stressed and others look fine

I've never tested nitrates in 10+ years. Gonna start testing nitrates when Hanna releases a handheld colorimeter if it's affordable.

Phosphates are .06 on a Hanna. This is low for my tank as po4 is usually .08-.10 in my tank over the last 4 years.

You should probably test NO3. If it's steadily increased over the years, it could reach critical levels. PO4 is even a bit high IMO. I aim for 0.00, hoping to be under 0.03ppm. NO3, I aim for less than 1ppm

NO3 could be high as I haven't ever tested. I've always vinegar dosed to control nitrates but never tested. My aim has always been off on PO4 but corals have done well especially Sept-March with PO4 around .10. Tried gfo and fozdown but never been able to maintain PO4 in the "ideal" range.

This scare is gonna make me a better reefer as I've had a long lucky streak just doing large regular water changes. Just hope I don't loose anymore large colonies.

Hrm weird, is anything stinging them? I had two big colonies come close and ended up losing both to stn,

It's possible but these corals have been intertwined and criss-crossing for almost 2 yrs with no issues.
