I have a problem with my salt mix IORC calcium is at 500 with salifert test kit. Has anybody else had this problem and how can it be lowered.

That is a tad high for that particular mix.

These ramped up salt mixes are ramped to counter usage, so, having
a thriving reef would deplete the Ca from your tank as it's designed to do.
What are you keeping in what. Particulars help a lot.

Is this 500ppm in the new mix or in the aquarium?

Is this a new batch, and have you tested other batches, or is this your 1st experience with this particular salt?

Did you mix the salt up right out of the bag/bucket? The Mg and KH does change
with settling, so I'm pretty sure the Ca can too.
I always took a new bucket of salt, poured into 2 empty buckets (outside)
like cutting a deck of cards, and continued blending them from there
a little here, there, and got the intended results from that particular batch.
Rolling a full bucket of new salt does nothing for it.
Shuffle the cards 1st then test a new batch before placing in Aq.

As for remedying the situation at hand, if it's in the aquarium @ 500ppm
your thriving reef will deplete it. I don't think Ca blockers/inhibitors were designed for aquarium usage :) so continued WCs with a non ramped salt
will eventually bring it back to normal. How much of this salt do you currently have?

If things haven't change a TON from the pic in your profile loaded last October
and this is the aquarium you're having this Ca issue with then
you should not be using ramped up salt, and if a LFS recommended it to you
then they made a dollar on you.

Yes this is the aquarium 55g 20g sump. I am almost out of this bucket and will be going back to normal IO SALT it has been high this whole bucket.
I have a monti cap, lord acan, zoas, toadstool, and what may be a gonipora? I mix salt in bucket before making a water change batch.
yes 500 ppm in tank at this time. I do a weekly water change of 5 gallons dkh was 9 on friday, nitrates 20 ppm, all others o ppm s.g. 1.025 ph 8.3-8.4

Do you have a pic of this? a FTS?
Mixing in bucket isn't what I meant to address settling.
I had a bucket of TM or TMPro that was weak on Mg at the top
and high at the bottom of the bucket. Always blended a new one
between 2 empty and the new made a 3rd bucket to get the salt all blended after that.
Glad this is near the bottom and not a new bucket full :)

It's a great thing to keep your Mg at 3x the Ca level (once in normal range)
and your Alk around 9-10. 10 Alk may be high for some SPS, maybe not.
To do this, it is ultimately best to become intimate with your reef, which will
then actually lessen your testing. Buy these 3 kits Salifert is fine.
Test daily, mid photoperiod for a month, and record your levels on paper
or in a blog here. You'll burn up your kits, BUT, you will know your systems
usage of these 3 most important elements to really good stability.
Very helpful for those who dose any or all of these 3 elements.

After this, you may not test more than weekly for a while then find yourself
comfortable enough to just check a couple times a month.
The Mg will typically stabilize but will begin a decline eventually, suddenly
sometimes, and it helps keep the pH up which I rarely ever checked.

I hope this is the pic you were asking me to post. I'm not sure what FTS is?
Thank you for your help.
forgot I mix up salt with a lg spoon dry in the bucket before making saltwater. Calcium has been high this whole bucket.

FTS is a full tank shot, was trying to get an idea of the coral stock
or possible Ca usage. Unless your tank is semi crowded with coral
and proliferous with coraline algae you probably don't need a ramped salt mix.
Semi crowded may not be the right term but trying to get across the Ca depletion point.

Someone with a thriving mature reef doing a 25% water change
500ppm weekly would not be an absurd replenishment rate really.

The issue to me, with using salt mixes to replenish what supplementation
provides is a bit on the unbalanced end of the scales. The animals deplete
Ca continually, WCs are performed at intervals that create swings in stability
when trying to maintain Ca, Mg and KH levels, as well as everything else.
Manually supplementing daily is a much smoother ride, and continual
dosing with a pump and controller is even more consistent, but also more
prone to automated mistakes and mishaps too.

I have been using IORC for three months now and have not noticed such high Ca numbers. I still have to dose Ca and Mg and they are still subnormal. Are you certain the test kit is right?

My Ca is usually in the high 400s using RC and I have quite a bit of coral - but only half is stony. Maybe consider switching to IO until you're stocked more in corals that'll use that Ca, as Japonicus suggested, or maybe a mixture of the two?

No how could I be certain without a Ca calibration solution?
Even the LFS could goof up or have a bum kit, but have you had them
check it? Is it in date? Is it a new kit? Details save time.

all kits are in date. I just purchased a salifert calcium kit because I was told API are not accurate. my API shows it at 440-480 ppm. the over 500 ppm is with the new salifert kit purchased first of march.

As for full tank shot I have tank in a hallway so almost impossible to get that. Corals are as listed monti cap 2"X 1 1/2", 3 head lord acan, lg LTA, 14 zoa polyps, a possible gonipora on top half of an astrea snail shell. I have little coraline algae in the tank. none on the glass anywhere.

I believe I will go back to the IO salt mix due to low coral load in the tank.

Thank you all for your suggestions and help with this.
