Don’t know what’s happening

Does anyone know what is happening to my coral nothing has changed in the tank

 

[wdebenedettojr]

Looks like it’s dying. What’s your alk?

Is that a Hollywood Stunner Chalice? How are the other coral doing? What kind of light are you using? What is your salinity?

 

[bettez8789]

I just checked the salinity it was 1.028 close to 1.030 I’m slowly lowing it and I believe it is a chalice of some sort

I don’t have a alk checker

All other coral are doing great

Until you buy an alkalinity test, expect to have a hard time keeping things with a skeleton. Doing frequent water changes with a good salt will probably help you keep alk in a decent range, but stability is key for anything with a skeleton and getting a decent test kit is the first step towards that.

What are you using to test salinity? Some methods are more reliable than others, and you want to be sure that your test is accurate if you're lowering salinity.

I’m useing a refractometer the one you set with greasy water and a screw and use your eye

Stupid spell check fresh water

Calibrating with RO/DI works in a pinch, but it’s much better to use a calibration solution. Since we’re testing salt water, we want to calibrate with salt water, because it’s more accurate than using fresh

Refractometer Calibration Solution

Keep your refractometer readings accurate! A refractometer is easily one of the most important tools to have if you own a saltwater tank. Without a refractometer, we would be guessing at how much salt is in the water, and more than likely would not be correct! Even if you have a refractometer...

See if they have anything like this at your LFS

I've the same refractometer. I calibrate it before every use with the calibration solution at 35ppt. A few days ago I checked RO/DI water, it was about 5ppt below the 0 in the scale. That tells me the instrument isn't accurate in whole range of the scale. As long as I stay close to the calibrated 35ppt should be fine.
I remember years ago when I bought the calibration solution people were saying in the reviews that was just expensive water and to just use distilled water for calibration. I don't regret buying it at all! I use it all the time and it's still half or more in the bottle.

Getting an alk test kit is pretty much a must if you’re going to be keeping coral. Highly recommend you pick one up

 

[thrillreefer]

Totally agree. Temp, Salinity, Alk, water motion and light are the biggest concerns

Salifert makes a good cheap Alk test. Like $0.10 and 5 mins per test

Alk

 

[bettez8789]

Alk

All is dkh 6 ppm gh/kh 107.4
Cal is 380

6v ery low

Very low
That would kill most lps

Where should it be at and what’s the best way to bump it up

8.5

Slow
Baking soda (cheapest too)
