That's awesome, thanks!

[jason2459]

Thanks for the addition. I'll get started again soon.

I test my water at 78 degrees after 24hrs of mixing@1.026. Test Alkalinity with Hanna Checker and Verified by Salifert. Test Calcium with Hanna (off by 100) and Salifert, Magnesium with Salifert.

HW Marine Reefer (Current Salt)

Alkalinity 8.9 dKH Hanna/Salifert
Calcium 420 Salifert
Magnesium 1280 Salifert

Red Sea Coral Pro (Tested small bucket)

Alkalinity 12.32 dKH Hanna
Calcium 480 Hanna 380 Salifert
Magnesium 1470 Salifert

Seachem Reef Salt (Tested 200 gal box)

Alkalinity 10.47 dKH Hanna
Calcium 527 Hanna 427 Salifert
Magnesium 1200 Salifert

Tropic Marin Pro Reef (Tested small box)

Alkalinity 6.6 dKH Hanna
Calcium 470 Hanna 370 Salifert
Magnesium 1350 Salifert

Instant Ocean Reef Crystals (Last bag from 200 gal box)

Alkalinity 8 dKH Hanna
Calcium 450 Hanna 350 Salifert
Magnesium 1080 Salifert

Waiting for Instant Ocean Regular and Coralife to arrive and will post results soon. I have been testing different salt brands myself after getting a real bad batch of Reef Crystals. I used them for years with success but I changed salts after these results. I also found my Hanna Calcium checker to be off by 100. I have Red Sea and API test kits on hand to verify when I have off the wall results.

now we're rolling

I have some spread sheet updating to do so went ahead and decided to test another salt brand tonight.

Aquavitro Salinity for reefs. I find it interesting they have on the label tested results from the batch this came from. Still doesn't mean something can't happen and results from a bucket can't be off.

Plus, they give quite the range for this to be in. Which goes to show that one should not expect one bucket or bag to be the same as another bucket or bag for any brand of salt. Basically what this entire thread is about. What can one generally expect from a particular salt mix.

Here's what's printed on my bucket. Lets see how close it is with the 3rd party results.

Something is way off on that IO Mg reading. Did you test again? Ca seems a tad low as well. Salinity level?

When you use the entire syringe you can refill and drip again. Each drop is 5mg/L. So you dont even have to completely fill it the second time if you know you're close.

 

[jason2459]

I just reviewed the other results as well. I believe you have a testing error of some sorts. RC Mg should also not be near that low and seems your salifert Ca levels are low.

Unfortunately I did there was only a difference of 20. My RC was a bad batch all other salts test fine with the same kit

 

[jason2459]

Ok, if there's a known bad batch I'd prefer to leave them out of this listing.

1.026 salts were tasted at the same time. Posted a vid on youtube doing it

I did not confirm if it was a bad batch I just assumed due to the test results. The other test are acurate as I have had no issue with Salifert test. The thread asks for Saltmix Parameters and that is what I posted. I recorded the test results and posted them on youtube. If there are inconsistencies in product people should be made aware as this is an expensive hobby.

There can be bad batches. Just like there can be bad reagents for test kits. First post states this should be for those times where things are going well to get a general idea of what to expect from a particular salt brand. A bad batch is not something to expect on average.

Heh. This statistics discussion had me looking at this thread of fantastic information and thinking to myself "really, what would be great is if we had averages, standard deviations, and lowest and highest reported values for each parameter of every salt mix."
Then I realized this hobby is a little crazy sometimes, and the salt companies probably aren't paying you a consulting fee for doing the job of quality control.

[jason2459]

So, do you want parameters that are known to be off?

I'm certainly not paid and have invested quite a bit in all the stuff I've been posting over the past year from test kit comparisons to this salt mix parameter thread.

 

[taricha]

I do think high and low ball outliers are worth noting, but - like you - I think it's deceiving to average them into your overall average parameter values, when they don't reflect normal experience with the product.
My last post was a statistics digression:
When you describe a set of data, if I only get to have one number - the average is the best one.
If I only get 2 numbers - I want the average and standard deviation
If I get 4 numbers to characterize a set of data, then I'd want average, standard deviation, maximum and minimum.

And your test kit showdown helped me make sense of stupid magnesium readings.
I'm mostly following this thread for the oddball trace element/metals contents of various salt mixes. You're doing awesome stuff around here, really valuable info.
