Ca increase without dosing?

[ckalupa]

Any ever noticed that there may be three or four days of calcium decline and the a small spike? I even re-tested and found the same higher number. Did not dose calcium. Any thoughts? Happened a couple times recently.

Thanks in advance!

Your not dosing kalk in ATO are you? Or dosing trace elements?

You can test your salinity.
Perhaps your salinity was going up.

 

[ckalupa]

No Kalk. No trace elements. Just the reef energy AB and fish food for the swimmers.

And salinity stable (ato working and holding 1.027 the whole time)

What were the numbers ?

 

[ckalupa]

This week 491,465, 460, 490. All with Red Sea test. Hanna meter seems to read about 75 higher but keeps the same track (just 75 higher). Salinity checked with Milwaukee

I belive that’s within normal variance of a hobby grade test.

 

[ckalupa]

I did not consider that. Thanks. Just seems odd that it jumps and a second test shows similar result.

Agreed! I doubt my ability to test exactly the same each time and expect a little variance.
