Kh Mag & Cal on the rise

[Bent17]

I am having issues with high kh mag and cal. I recently switched from Aquaforest reef salt to Fauna Marin Salt. My current vaules are:

Kh 9.5
Mag 1500
Cal 490

Dosing twice weekly AB+ and Fauna Marin Coral dust.

Could it be one of the two are increasing the above?

ReefEnergy AB+ and Fauna Marin Coral Dust - no. Different salt, definitely. Did you test the parameters on the new batch of saltwater before you performed your last water change?

No I haven't. Dont know why its increasing. Kh is always at 9.5-9.6 and mag starts at 1400 and ends up 1500 and cal 450 and ends up 490. Now either my corals are not yet comsuming anything but I have coraline on rocks and my wave makers are all covered

That's from the container, yes? I meant, did you actually test it after mixing it up?

No I never tested the mixture before I do a wc

Sometimes (rare, but if happens) you get a batch of salt where the parameters are off. If you switched salt and your parameters soon changed - that's probably the first place I'd look.

I agree: test the mix. You might actually have salinity higher than you thing, rather than any problem with the batch.

You do replace evaporated water with fresh, right, not seawater?

Yes have an ato with gravity and always at a constant 34 salinity
