why can't acros survive in my tank

[Greg Hiller]

Guilty as charged, however, it would also be nice to know what color temp and bulb manu. and age of the lights they were under. I'm just trying to figure out if they were shocked by light.

>i dripped for 1 hr with iodine <

I hope you don't mean they were in an iodine bath for 1 hour? The standard bath is 10-15 drops Lugols per liter for 10-15 minutes with an airstone for circulation.

i changed my bulbs last month 10,000k
his were10k too dont know how old?

I'd suggest you get an encrusted chunk of a hardy Acro (the Larry Jax purple tip comes to mind, just about every member of the club has one) and just plunge it straight into your tank. If it's still alive in 3-4 weeks, then I think your tank is safe for Acros, and the problem might have been due to something else.

opps i did drip for an hr
but do you think if that affected them they would have lived 3 weeks
they had nice color and the living chunks i broke off the last one still have nice color brown ice blue tips

those were test frags my tanks been screwed up for six months or so now i lost alot of frags awhile ago they all died one by one over two weeks time all
that survived was a few frags of digita from my large colonys
i filled almost a 5 gal bucket with dead colonys
im thinking of just breaking down and starting over again

OK, I need some clarification....

The tank is two years old...were you EVER able to keep SPS...or have you just been trying for the last 6 months?

yes for a year every thing was great then it all went down hill
i lost some pretty large colonys

Was there a particular reason that you were able to pinpoint that was causing the problem before in your tank?

no i havent found it

Did anything occur just before you started to loose the colonies 6 months ago? Did you have any new coral additions? Any large changes in routine? Add substrate, remove substrate? New pieces of rock? Start dosing something? Temp spike? Low alkalinity?

 

[jovreef]

Was this a new tank or a second hand one? I'm almost thinking it could be something chemical... maybe someone used medication in that tank before, it absorbed into the silicone and started leaching out just enough to kill the acros?

well thats my problem i added so many things
i couldnt figure out what it was
i added a reactor,stopped using 2part, ph monitor,substrate,caulpra

so what i did was removed them al one by one over the last couple months
i thought i was having ph problems because of the reactor , so i removed that ,the monitor was reading 7.6 come to find out the probe was broken after thinking my ph was low for months i bought a new ph test kit
and found it was fine , after that my parameters checked out fine
but my surviving digita wasnt growing at all , i removed all my grape calepra thinking it was releasing toxins because it grew really fast with alot of die off turning grey
so i threw it all away

greg one more thing i did before all my big colonys died
i used oceanic salt the week before they died i beleive thats what killed them
i changed 50 gals with the stuff cause i got a bucket really cheap
after always using io it raised the calc to 500

 

[denvig]

I’m guessing AEFW or some other infestation.

 

[NateHanson]

How big is your tank? Even if it wasn't the oceanic salt, it might have been the shock of a really big water change (if everything wasn't matched exactly) that shocked the corals the first time.

75 sho 125 sump

 

[NateHanson]

That's not so big a water change then.

Did you airate or run a powerhead overnight before using?
Oceanic tends to mix at a very high PH ...I've see it as high as 12
