Okay, as promised I have mixed up a batch of this New Formula Red Sea Blue Bucket Salt and the results are below.
I prepared 14 litres of Salt water following the procedure set forth at the bottom of the page at the following URL.

Steps taken were:

Salt was rolled around to mix up as much as possible.

Add 13.5 litres of RODI water to the mixing vessel.
Water TDS was measured at 0 ppm.
The water temperature was 22 degrees C as that is ambient temp here at the moment.

Added 534.8 g of Salt as stated at the link above (however I expected that this would be incorrect as it appears the page has not been updated to reflect the ‘New Formula’)

Mixed for 20 mins.
At this point the solids had completely dissolved as stated in the salt specification.
Added RODI water to achieve a volume of 14 litres and temperature raised to 25 Celcius

pH was measured at 8.21 (Calibrated Milwaukee MW102)
Salinity was measured to be 31.5 psu using a calibrated Hanna HI 98319 Conductivity Meter and crosschecked with a calibrated Milwaukee MA887

Added additional 29.4g salt (product spec says 4.3 gr/l which would be 564.1g)
Mixed 10 mins

Salinity was measured to be 33.1 psu

Added additional 40g salt (total 604.2g) and mixed another 10 mins.
Salinity was measured to be 35.1psu

At this point I had used 604g salt for a total volume just a tad over 14 litres of water @ 35.1 psu.
So you require 43.1 gr/l of salt to obtain 35 psu compared to advertised 40.3 gr/l


Tested results at this salinity:

Alkalinity:
Hanna HI772 8.8 dkh
Salifert 8.8 dkh (0.43ml)
0.1N HCl Titration 8.7dkh

Calcium:
Hanna HI758 424 ppm
Red Sea Pro 430-440 ppm

Magnesium:
Red Sea Pro 1280-1320 ppm

Nitrate:
Hanna HI782 0.0 ppm

Phosphate:
Hanna HI774 0.01ppm

Total Ammonia:
Red Sea Pro 0.0 ppm

So, this appears to be a good salt. It leaves no residue in my mixing vessel and was completely dissolved in under 30 minutes as stated.

Most chemistry appears to be within spec according to hobby grade tests.
Alk is higher than specified and slightly more salt is required than advertised.


Edit: This is the red sea batch ICP for this box.

i wish there mag was higher around1350 i hate how it mixes so low lol
You could simply add about 42g Magnesium Chloride Hexahydrate per 100l when mixing your saltwater to increase Mg from 1300 to 1350ppm
