View Full Version : IO Salt Ca Outrageously Low!

So I tested a newer 160g bucket of IO salt, purchased from my local PetSmart. At 1.026 / 35ppt it tested 325 ppm Ca!!! :eek2: I've been using IO salt for many years now and never have I seen it this low. It's always tested around 380 ppm. This is just stupid low to me. I'm thinking of calling IO on Monday to complain. I tested twice with a Salifert Ca test kit.

What is everyone else's IO salt Ca levels testing? Please test at 1.026 on a new bucket/bag if you have it.

That sounds like a container of the old formulation of IO, which ran about 350 ppm, if my memory is correct. The new formula should be around 400. You might need to mix up the container to get all the chemicals evenly distributed.

How old are your test kits?

Mine usually tests at 350 and I've experienced this for a long time.

Thanks guys. I'll mix it up a bit and retest. 325 just seems awfully low even for IO. My Salifert kit isn't very old but I bought an API tonight as well.

I just bought the 200 gal box IO version about 3 months ago, and it tested 420 with an elos calcium test kit.

Are you talking IO or Reef Crystals? If you expect/need higher cal why not use the RC?

My last batch of IO (200g box) mixed at 1.026 had a CA level of 400. I'd definitely give IO a call. Maybe it's a bad batch.

Canyou tell that you if you got the IO in the old/new version from the out side of the box?

I am gonna be finishing up mixing my IO and will test and post back also, however I have the 200gal box from fosters.

as far as I know there isn't a way to tell the old from the new from the bucket, but I haven't bought any buckets sence the boxes came out. I already have way to many buckets lol.

I got 420 with API and a sg of 1.026 with refractometer

I just got 400 on the nose @35ppt. I always get the 200g box and mix up the bag before opening it.

is it IO or REEF CRYSTALS. i know my IO that i used to cycle my tank only checked 320 with API test kit. but i was told that was a normal reading by a couple ppl on here for just plain IO

It is IO. With reef crystals I was getting over 420 if I remember right.

I am using IO. they have changed the levels in IO lately and now they have higher levels.

i just tested my IO mix. This is off a chemistry analyzer at work.

sp grav 1.025
Ca 370
Mg 1165


which is fairly inline with what IO claims at 1.0264
Ca 400, Mg 1350

Guys, it is straight Instant Ocean. Not Reef Crystals. :) I didn't know until recently there were new/old batches and they are including more calcium in the newer buckets. I'm going to call IO and see if I can't track down the issue. ;)

Its not really new and old reef crystals is for people who want to build a reef and the plan insteant ocean is ment for fish only tanks so they dont put alot of elements in it because there will be nothing feeding off it but algea.

I always buy the 200g boxes too, so maybe I have just gotten some of the older batches.

IO salt isn't just made for fish only tanks Ethan Music, nor does algae feed off of salt mixes. ;) You'll find with more research many users are highly successful using many brands of salt mixes including IO.

OK guys, I just got off the phone with a representative at Instant Ocean. He says the salt formulation has NEVER CHANGED (regardless of the batch). There is no new or old formula for IO. He said the range has always been 380-475 ppm. He also said I could send a sample in for testing and they would determine if it's in their advertised range. So there you have it, myth busted. :)

It's very possible the mix had just settled in the bucket as to get an inconsistent test result. I'm not very proactive about mixing up a new bucket, especially a full one. I'm going to mix up what's left and re-test. I'll keep you posted.

I don't believe that's accurate. I think they were even advertising the new formula, and people did a lot of tests when it was delivered.

I don't remember there being any special labeling but do remember a lot of buzz about it and in general everyones numbers where higher with new batches. I'm sure there's talk about it in the master salt mix test results thread. I wouldn't trust a company rep as that is either the company stance now or he just doesn't know.

Well, unless someone else around here has connections to someone higher up than a phone rep... But the statement I posted earlier was the information given to me. :) Company stance or not, I don't know why one would believe anything other than what they tell you without scientific evidence to back it up. The only thing you could possibly do is have the salt tested by an independent lab but it's still a he said/she said game even if there are less than advertised results found.

Nothing scientific behind what a sales rep tells you. I'm sorry, but I just don't trust anything a sales rep says. Though, I have no idea why they would lie about this.

I buy it by the bucket and the last 3 measured 420 ppm @ 35ppt.

The new buckets look a little different too but I go by the 2009 copyright stamp. They seem to be at 420 with the 09/10 stamp.

I know insteant ocean is not just for fish only but they have 2 brands of salt reef crystals and the plain insteant ocean mix. In their reef crystals brand they add more calcuim and trace elements. In their plain Instant ocean mix they just have the basics which I been told does not have the extra calcuim and trace elements.

Don't know if this helps I might just be off topic and I know algae does not eat salt but some of the reef mixes add more trace elements in the tank helping corals and if you go with a fish only tank the only thing that will benifit from this is algae. Thats what I ment sorry for the confusion.
