Urgent! All my corals dying!!!

[CuzzinScuzzi]

So I did flat worm exit like a month ago, 2 treaments and before i hooked my sump up to my i probably flushed 100g of fresh r/o water through my sump without it hitting my display tank. Now fast forward to 4 days ago, all my corals are starting todie.

Sg 1.025
Amon 0
Nitrite 0
Nitrate ~10 (if that, the vial barely changes color)
Temp 78
Phosphates .03
Calcium is 440

I have leds @60 watts
No over activity in my protein skimmer
No over activity as far as algae goes
No aiptasia

Tank mates are:
Watchman goby
Occelaris clowns x2
Kole tang
2 peppermint shrimp
Hermit crabs
emerald crab

I feed once every 3 days or so with shrimp/plankton/clam whatever... i cant figure this out... nem and fish are fine and the nem isnt anywhere near my other corals... so far ive lost a plate, seriatopora, frogspawn, mushrooms... if anyone can help in anyway i'd appreciate it... im out of ideas... i put in a few drops of lugols to if there maybe is some type of toxin in the water/ oxygen but to no avail. Thanks! Its a 85gallon system with a 65g display 20 gallon refuge housing seaweed, grape and cheato.

Lugols is iodine and won't detoxify anything. It may kill some microscopic life, but probably not in that volume of water. To much iodine can do harm.

If you suspect toxins, the best corse of action is to do the largest water changes you think you can get away with and run good quality GAC.

Your parameters are fine l. Hopefully you're using a calibrated refractometer. Very important.

Are you new to keeping corals? There's a difference between stressed corals and dieing corals. Links to pics & an enhanced explanation would help here. Good luck.

Excellent advice here. Didn't come to my mind. I don't like radical cures for small problems so have never used the flatworm exit product. But I've heard that you must follow the directions completely & precisely.

Water changes & carbon!

Check your ph. Maybe your alkalinity is tilted towards the acidic side.

Alkalinity?

One of the big three you should test for ,when alkalinity swings Coral often die..hth

 

[CuzzinScuzzi]

My ph hasn't swing at all its steady at 8.2 and what is weird is that my corals have been growing exponentially since i put them in. I forgot to mention that my xenia has been done throughout this... and unfortunately my ability to do water changes is limited to about 5 gallons per night due to my ro filter...

I didn't know carbon could take toxic chemicals out of the water maybe I'll try that. I have been doing them thougb, ive swapped out about 40 gallons already...

ph does not equal alkalinity

^ Oh yea right. Good thought. Forgot to ask about your alkalinity and magnesium. Geeze I was focusing on what was added, not what might be missing. Really low or absurdly high levels can CERTAINLY hurt your corals. I'd get high quality kits ASAP and test.

 

[CuzzinScuzzi]

Yeah my ph has stayed constant, unless your talking about kh?

 

[ricks49reef]

If you didn't run carbon as instructed when you did the flatworm treatment ,the toxins from the dead flatworms has probably caused the problem.You need to run carbon plus the water changes right away.

 

[CuzzinScuzzi]

Testing my kh right now ill post a picture...

 

[Highweigh]

Never hurts to run some carbon + water change or at the very least some carbon and see if that helps

 

[CuzzinScuzzi]

Yea at 11-12 degrees... ill try to get some carbon tomorrow, i live too far from any pet stores to make it... thanks for your guys help...on the salifert box it doesn't say to run Carbon after

 

[CuzzinScuzzi]

11 degrees ok? Ill try to get some carbon after work tomorrow and see if that helps.

 

[CuzzinScuzzi]

The picture is whats left of my frogspawnfrag...

Kh is a measurement of alk. I consider 11dkh to be high, but I can't say it killed your corals. Some people do ok at those levels. I'm not one of them. I like 8ish. Magnesium is super important also. Low mag causes problems.

 

[CuzzinScuzzi]

Ahh gotcha...

I've never ran flat worm medicine, but this guy sounds like he's onto something

 

[Reef Frog]

^Yup. Cuz has a few possible issues going on all at once. Hard corals don't like that. They crave stability.
