Calcium wont go up?

[MichaelReefer]

All of a sudden my Calcium is reducing and not going up, even with my Kalk Stirrer and doser.... I tried manual dosing some calcium and increasing my doser but it is still reducing. Anyone know what could be going on? (ignore the salinity, it's always wrong)

Try bumping up your Mg gradually to 1350 or so. Had similar experience and it helped.

Calcium does look fine, btw, but I'm suspect you are wanting above 400+?

How many tests do you have left on the Trident's Reagents?

64% remaining Reagent.

I would do a manual test to verify the trident reading before doing anything else. When a test shows a unexpected result its always best to confirm with a different tester.

Looks like your salinity is on the lower side which may be a strong contributor to overall lower parameters and will not elevate. Also, the Mg is much too low as well, north of 1350, your Ca & Alk are just going to combine very quickly with Mg that low. When this happened to me I did several water changes, like 20% over several weeks. Note: Please do not add salt directly to the tank. Slow is best. Good luck!

OP stated that the salinity wasn't the correct reading. Which with an apex I'd be more surprised if the salinity reading was correct

Apex Salinity is always wrong. Ask anyone that has one. I test with Hanna. Its 1.026

You would think, but its the ONE bad thing about the Apex. Haha

Mine stays at around 33.5 at all times also, regardless of what my salinity actually is. I've considered installing the VCA salinity probe stability kit, but haven't decided yet.

Right thank you - and which is why I pointed out that his elements are so low. Man this forum is quick to start flaming!

All I did was point out that the OP's salinity probe reading wasn't correct per his original post. Sorry if you somehow took offense to me pointing it out.

ETA- I'm not sure why would his salinity probe reading low effect the reading of his trident?

I would do a test with a separate and reliable test kit before doing anything major and then adjust the calcium to around 430 or thereabouts as necessary with whatever additive your using.

i would also double check magnesium and bump it up to around 1350
