Cant sit back and let my corals die

[duke62]

No. i always use gloves when i put my hands in the tank. i use latex if just my hands are going in and sleeve gloves when i have to get my arms in

This is depressing. I hope your corals pull through. You are (sadly) not alone. I have 2 cases of RTN right now. Hoping it will not spread. It started on a colony of Tricolor from Sanjay and spread to my prized pink lemonade colony. Had to chop both up today
Funny little irony is I just bought a large order of nice sps frags to restock some stuff I lost in my move and noticed the RTN as I got home with my box of corals. I think the most horirble thing about RTN is I have no clue what caused it. I didn't touch anything in my tank and things were going fine since the move. I only added some chaeto in that time and I highly doubt it was that. I did up my dosing of Alk and Cal though...

I was just throwing it out there. Sometimes people forget the little things. Good luck man. I hope you find a solution.

Well today a jesus stag has gone,tri color validia,pink lemonade and a tort. Jesus stag has been ith me since i started sps along with the validia

 

[duke62]

well the past 4 days things seem to be stabilizing a bit. No new STN on remaining corals but the couple that are really stressed and far into the stn are still going but i havent noticed any new cases and my bonsai that showed little STN has stopped

Fingers are crossed for ya!

+1 good to hear

 

[duke62]

Counted my chickens to fast. being way to hopeful. Woke up today with a fully dead red robin stag my joe the coral which is a big colony that i cut the base off last week has begun STNing again and my bonsai colony has begun to STN again. Nothing has worked that i tried and im out of hope

How long has the tank been setup? Have you disturbed the sand and/or rock?

 

[duke62]

Tank has been up for 3 years and never disturbed the sand bed or rocks

Try antibiotic?

 

[fishman1069]

This my be a long shot but im thinking DOCs. Dissolved organic compounds built up in your rock and sand and are now leaching into what used to be a low nutrient system. Its shocking your SPS and its STNing. Im thinking the build up happen because you never moved your rock and sand. What makes it leech, i have no clue. They typically call this "old tank syndrome "
Again, its a long shot but maybe something to think about

I'm pretty sure we have been through this, but when was the last time you calibrated your refractometer with a known reliable standard?

 

[duke62]

what antibiotic MBG?

 

[duke62]

Pratt i got a new bottle of solution about a month ago maybe 6 weeks. My old calibration solution was wrong and was of by .06. so when i thought my salinity was at 1.025 it was really 1.019

I think that is the root of your problem. 1.019 is really VERY low for Acropora. Even though you corrected it weeks ago, the stress may still be rearing its ugly head. There is no way to know for sure, but stressed corals are more susceptible to a whole host of issues.

 

[duke62]

That was my original thought as well but my chalices,birdsnest,some zoas and montis are also going

 

[duke62]

Hey Randy. Can i be over skimming and stripping the water of to many nutrients? I have a reef octopus 3000 rated for 300 gallons but my tank is only 100 gallons TWV? Even though it skims my tank like a beast

 

[prattreef]

It is possible. My corals are happier with some nutrients in the water---I target @ 5ppm NO3.

 

[duke62]

my nitrates are around 5ppm using salifert
