Calcium Levels Too High? Problematic? (API Test Kit)


TRT,

Hey everyone as a usual "reefer" / hobbyist you should test your parameters. Right? Well, tested my parameters this morning and came into disbelief with my calciums levels. So, I ran the test twice and came with the same results. It took me 36 drops of the 2nd solution to achieve the clear to blue. If I am correct in calculating the level is around 720. (Every drop is an increase of 20 and the last number in the chart is 26 drops= 520) (36 drops-26 drops=10 extra drops) (10 drops x 20 calcium variables)= 200 + 520 =720. I am not strong in math, but I know I am right lol.

The real question is would this hurt anything?

Current Live Stock

Fish
2 Snow Flake Clown
1 Bristletooth Tang
1 6 Line Wrasse
CUC

Corals
1 set of Red-Blue Spotted Mushrooms
1 Finger Leather (not looking so good)
1 set of Red Mushrooms
1 colony of orange Zoos with green center

I would double check those readings with another test kit.
What are your alk and mag readings ?
Are you having any problems with calcium precipitation ?

I'm using the same test kit for calcium and alk.... ALK is at 17 and Calcium is at 720???!!! I'm going to take some water to my LFS soon and test mag, calcium, and alk. I have no percipitation either so I have no idea. My PH is at 8.2-8.3 constantly so idk if the test are crap or my magnesium is extremely high or low.

My most recent test results put me at an extremely low alkalinity and a ridiculously high calcium level. I have no precipitation and I've had corals splitting and reproducing and my anemone is growing like crazy so I'm not real worried. Weird thing though, I've not had any coralline growth in the new tank except in low lit areas.

I don't have a mag test kit, if I did I would check that also. I have never managed to find one at any LFS in my area. Might just order one of amazon.com or dr.fosters.

I figured if my calcium is high, than my magnesium should be too. From what I have read, is that calcium won't stay in your system without magnesium being stable rate. My assumption is that my magnese levels have to be high also, if I am right.

Far as having any problems with calcium precipitation, I don't think I do?

If calcium is high, then also your mag levels are high as well. Calcium won't stay in the system without the magnesium at a certain level.

i am no expert, but i would have thought if that test kit is right you would be seeing calcium in the tank. just my 2p for what it's worth.

Not sure what you are referring to here. My API test has the color going from Pink to Blue. Each drop is 20 ppm but why your beginning color is clear I have no idea. The kit may be bad. Have your LFS do a check. Too many aquarists do not check their Mag. I just don't understand that.

+1

Same thing happened to me with the API kit, but I only had 6 extra drops.. went to the store to have it tested and they said it was 420..went home, smoked a bowl.

Calcium and Alkalinity are also related to salinity, if your salt levels are running to the low side and your calcium levels are actually on the high side then they will appear to be higher in the tank than they actually show in the test's. We have to remember that the tests are designed to be rapid and not confirmatory. temperature plays a role as well, the higher the temperature the more calcium that cam be absorbed into the system. High calcium isn't a bad thing, keeping the alkalinity high is the issue. Usually the alkalinity drops significantly and then you can have a pH drop in the water. Calcium, alkalinity and pH are all related and if Calcium is high and their isn't a buffer in the water then the pH can change dramatically.

What I am reading, is that your calcium is high and your alkalinity and pH are being maintained, if this is the case then I would keep monitoring with a cautious eye but not be to alarmed.

Calcium can also increase if there is a source of CO2 being added to the water or CO to the water. This can make a weak acid and dissolve the calcium in the sand and rocks and eat away at the alkalinity as well. Maybe some fresh air in and around the sump may help. High phosphates can cause phosphoric acid in the tank however you should see a drop in pH if this is happening.

Maybe, mrplum you can help me out, so I am going to go more in depth.

First, I dip the testing tube into the DT and fill it to the 5ml line.

Next, I added 10 drops of solution #1, like it is instructed. I mix solution #1 before I begin to add solution #2.

The result of that step, is that I get a milky looking color in which I consider it being clearish/whitish. (Sorry for the confusion)

After that I begin to add one drop of solution #2 at a time and mix.

By the 10th drop that is when I began to see and actual solid PINK and it took me 26 drops after that to get to BLUE.

Do you have to achieve the PINK color first and begin counting drops? If so, then my calcium levels are fine. Or start counting drops after adding solution #1? If that is the case it took me 36 drops of solution #2, then it will equal 36 drops x 20ppm = 720ppm

Am I doing it wrong? Or...is the test kit just bad? Am I suppose to see pink in the test tube after applying solution #1???

Interesting query. I never thought about it, but now that you posed your question, I did a test just now and looked for a definite color change at drops 1, 2 and so on. I say that because when I do my testing I just always add 17 drops of #2 because that is 340 ppm and if the color would come up blue I know it is low as we should maintain the 360-500 ppm range. So, at drop 1 I didn't see much color. At drop 2, a slight pink (barely) but at 3 I did see pink although faint. By drop 6 it was definitely pink and got progressively darker until of course it turned a good blue. Hope that helps.

So, if your calcium levels do get the high, how do you reverse this??? water change??
