Is this RTN? Will is spread to other frags?

You could save it probably but I personally would just chuck it rather than making all these changes. Green slimers are a plenty and cheap.

I'm going to use some Tropic Marin Pro salt, will do w/c today

Drop alk, im surprised your not burning the tips of your coral. Also STN vs RTN I consider Rtn to completely peel in 24 hours. STN is over a few days. Also do something to bring no3 up. Your starving these corals
This has been progressing over a few days. How can I bring no3 up in a coral qt? I keep ghost feeding and will add some algae pucks. Other ideas?

As others have mentioned, your alk is way too high. I would let it slowly drop on its own however. Think of Alk kinda sorta as a gas pedal and Phos/ nitrate as fuel. You don't want to floor the accelerator if you don't have much or any fuel in the tank. Even with slightly higher nitrates and phos, 10 alk is really high. In my experience keeping it slightly above sea water levels has always worked out best (7-8 DKH)

Would you suggest something like ME Nitrate (saltwatersquarium) or Sodium Nitrate (amazon)? None of the local shops carry anything.
Amazon sodium nitrate. 85 grams per liter of RO.

And yes, IO as well as IORC both mix very high dkh. The TM stuff will mix closer to 8-8.5 which is better for a low nutrient tank and one that does not have much Ca and ALK consumption.

Cool, thanks. I have a 20g QT, how much of that should I be adding to that? (sorry, still newb)

I'm mixing up some tropic marin pro tonight :)

I just did a quick calculator search on R2R and I see others are running a much more diluted solution than I do.

Start with a 5 ml dose and measure 1/2 an hour later.

As to the frags, whenever I get RTN I cut well into the live tissue, remount, and move to lower light location for a few days.

Thanks again. I'll try and find some of those calcs / posts. 5ml is quite small so I'll want to be accurate and safe. The awc will start tonight with some of the tropic so that'll slowly start to bring it down too. I'll chop that frag up :)

Ok, using this calculator (http://www.theplantedtank.co.uk/calculator.htm). It looks like adding 1ppm/day is a safe amount based on some forum reading. To add to 1ppm to a 20g tank it looks like 1g of NaNO3 added to 8ml of RODI water then dosed will do the trick. This is the Sodium Nitrate I was going to purchase: www.amazon.com/Duda-Energy-5sn-Fertilizer-Industrial/dp/B00KZOECLE/. Anything seem off? I read somewhere about multiplying by .84, but I think that was if the sodium nitrate wasn't lab grade (unlike in the amazon link)

Argh. I cannot find the thread where I got my solution instructions from. I used Loudwolf sodium nitrate and then a more generic sodium nitrate that was 99% as well. You should be fine; just keep testing.

OK thanks. I did some reading I think this should work. I've also read I can use muriatic acid to drop dkh. Not sure if I should go that route but I made a calculator for that in excel (I just like math) and I have that stuff on hand. I used a post from randy that went over the calculations. Does anyone do that too? I read some do that for IO when mixing it.

Moved the slimer frag off and chopped it up. If it is saved, cool. Mixed up some tropic marin pro. The awc will take a long time to reach the QT so I did a small 5% change. DT and QT changes 6% a week but the QT comes from the dt which will take a while to change over at that rate.

Ok so I lost the slimers that I tried to save, no big deal. Everything else is OK rtn wise, just a little browner than I'd like, I assume because my nitrates are low? I was able to slowly bring dkh down. I did this will small water changes of trop pro.

Dkh 7.62 (Hanna)
No4 0ppm (lr hanna, not ulr, buying Hanna ulr)
No3 1ppm (nyos)
Ca 562ppm (Hanna)
Sal 36.2 (Hanna, a little higher than desired, will slowly drop)
Tmp 78.2* (Hanna)
