Emergency my frags are dying

[01xp]

Help please so I had a spell of bad luck and lost a bunch of frags randomly
One of which was my homewreaker.......
Anyway my last to surviving frags are my Walt Disney that I've had for almost a year and a Oregon tort that's been with me for 4 months. All my other frags that died started the same way tips and base started to loose color the polyp lose then dead please help I've tried feeding and water changes my numbers are as follow.

Calcium- 416 Hanna
Ph-7.8 Hanna
Phosphate- 0.47 Hanna
Alk-8.4 Hanna
Mag-1240 red sea
Temp-81.4 apex
Salinity-1.023 refractometer

Salinity and mag are a little low. Also no nitrate reading.

Your PO4 is very high. Should be .03 - .13 ish.

Right now the only nitrate kit that I have is a expired Api (waiting) on ups do you think the po4 will do it? I have some gfo running right now to help

 

[blasterman]

Phosphate at .5 is a BIG problem. I'm going to guess your nitrate will be either super high or 0.

So drop phos and nitrate?

I wouldn't do anything until knowing where all your parameters are. Maybe a larger water change is best for now.

prob around a 20-30% water change while you wait for the new tests to come in, why run the salinity so low at 1.023 though, just curious?

I'll do at 15 gal water change it's a 75gal tank the salinity ive been going off the apex and it says it's good I usually try to stay around 1.025 I guess the apex can't be trusted it says I'm at 1.026

The only thing I trust is a refractometer with calibration fluid

Hmm. Should I decrease my phosphate? It's at .2... everything is thriving and colors are improving

I don't consider myself an SPS expert, but I try to avoid making drastic changes when things are colorful and thriving.

From reading so many threads I have to agree with the trend here. Stability is often more imported than any number. Even the values we all go for are so many multiples higher than corals home base in the ocean so it’s not like we’re at all able to equal that. Enjoy that what you’ve got going works.

My PO4 meanders between .1 and .2 and that is about the time I hit the tank with Tropic Marin Elimi Phos (lanthanum chloride) at the recommended dose level. General sets my PO4 back to .1 or a tad more.

Having been through dinos a few times, I don't go any lower.

pH of 7.8 is a bit low too...shoot for something above 8.0, at least. Move slowly though, as with most anything in this hobby.

Sorry for your troubles.

Did you get a nitrate number yet? I have found that when one nutrient gets out of whack high, the other can suffer the reverse. I don't understand the mechanics of it but it seems very common.

It is going to take a while to get your PO4 down safely. And it should take a long time to avoid shocking your remaining sticks. GFO will certainly do, but I personally feel more comfortable with liquid (diluted) lanthanum chloride. I use Tropic Marin but any aquarium brand will do. It is easier to dial IME.

So my nitrate are about 25 to 30ppm
And this is how my Walt looks she's a gonner. I'm thinking stn.
So I ordered a new sump and a biopellet and gfo reactor well see what happens save my pennies for more sps
