I test my waters and it is 960 ppm ! No LPS or SPS inside but recently I dose calcium solution according to whatthe instruction say. The purple coraline on the LR I just got seem to be fading away ( I never have coraline growing in my tank ). Calcium this high is it a problem ?

do you have an alkality test ? i'd guess it's really low and that is a problem.

Calcium up there is a problem, but I'd let it drop on its own/with normal water changes. What is your alkalinity?

What test kit are you using? If you have no LPS, SPS, or clams, you shouldn't need to dose calcium. Even if you had maybe 1 clam you wouldn't probably need to dose the amount the bottle recommends or 1 SPS etc. I would do a 10% water change. Depending on the salt you are using, calcium in newly mixed water should be 390-440ppm. I don't think it would hurt anything if you let it fall on its own.

I doubt your results are accurate, the calcium would precipitate out of the water if it were that high.

9 dKH? Yes, your Ca is high, but it will fall to an equilibrium point on its own.

I using salifert to test. But what can be making my coraline fade away when the LR are in for about a week or so? I thought is was low calcium at first but now I don't know.

you tested wrong, your water would look like snow

I did it twice though, should not be wrong but there is a thin layer of white like oil on my water surface calcium !?

I think the salifert chart only goes up to around 500 or 550ppm, doesn't it?

Explain how you are using the test kit. You may be getting a step wrong.

I use the reduced amounts so I can do more tests and it say multiply by two before the multiplication it was 480ppm.

Try the regular one once and not the reduced and find out what you get.

are you sure the color isnt changing before you stop? youre using half a scoop and 4 drops and you have the air bubble in the syringe?

I did again with the standard one and the 1ml was not enough to even change the colour of the red solution. So the 960ppm has to be right. And yeah the process was right.

it cant be right, it would look like a blizzard in your tank

are you multiplying the ML on the syringe by 2 or the calcium reading

I did a standard test and I do not need to multiply but 2 and yes I see snow particles in my tank now, small though.

what size is the tank and how much of what brand of calcium did you put into it? Youre going to need to start changing out the water. Like 20% at a time.

Pro series calcium 50 gal tank and I plan to do a water change but how much I still not decided.

Not sure where you are located, but I would have a store or someone from a nearby reef club also take a measurement for you.

I second hans1976, take it to the LFS and have them test it, or if there is a local reef club ask a member to test it.
