New IO levels?

[Atomikk]

I had an extensive chat with a person at Instant Ocean regarding salt perameters in general. The very important point a lot of people don't know is when you test your salt, it has to be a certain temperature and salinity to read properly with your test kits. I could be wrong, its been a few weeks since MACNA, but the testing salt has to be at 1.025 and at 78deg F. Only then you will get accurate readings from your test kits.

The Instant Ocean batches of salt had always been high in Ca (420), but a lot of people were testing their batches in 80' water, or 1.024 salinity, and were getting smaller readings. They saw that this was their main problem, so they bumped their calcium levels to 440ppm just in case people test at inoptimal levels.

In other words, the new IO salt is set at 440 Ca, 9dKH and 1350ppm Mg.

If that is true, then it would be a Great news !
i am using DD now , switched from KZ, and used reef pro before that. All are the most expensive salts and they all are not perfect to say the least.
if IO is what they say they are then it is what i will use, because high cost salts are coming and going but IO is seems to be available all the time.

I just tested mine with salifert test kits, mixed for 48hrs at 78 degrees and 1.026 sg. The bucket is sporting the new design on the front

Alk 9.6 dkh
cal 370
Mg 1170

While I have no idea how accurate the test kits are, I find the corals and coralline do best in my tank with Alk at 9, cal at 380 and Mg anything over 1250 using the same kits

that's around what the old pails tested.

My IO salt has been reading:

Mg 1280
Ca 380
dKH 9

Salinity 1.026
Temperature 78 degrees

This latest batch was from the 200G boxes.

My old pails were testing at alk 10-11 dkh, cal around 340 and Mg at 900

Just got a new bucket., not ready to make a batch with it yet, but soon and will test. i had an old bucket of IO, and having a heck of a time with MG/Ca hope the new stuff is more consistent

I call bull crap on this (no part on you though). Manufacturers will claim whatever they want, but the proof is in the bucket. I will believe it when I test the bucket!! I always test at 78 degrees and 1.026 specific gravity, which according to the claims of the manufacturer should put me higher than the numbers you listed. Like I said, I will believe it when I see it! If for some profound reason the manufacturer is actually representing the product honestly (how many snake oils are there out there??) that would be awesome!! Albeit I would rather have to dose calcium to the mix than have my calcium as high as 440 ppm (or higher with the higher SG).

My "old" buckets have always tested around 360-370 ppm calcium, almost always 11 dKH alkalinity, and 1170-1280 Magnesium. Magnesium has always fluctuated significantly, but I have never had it test less than 1170 ppm.

I will get more info from them on how to properly test your salt. Again, its not just test and go. There are certain rules you must follow. On that I will write later on in my blog.

Here is a thread that had been going for a while on RC.
