Aquavitro’s new Salinity salt is aimed at the natural seawater parameter (NSW) crowd which is popular among ULNS users. Aquavitro is Seachem’s new brand that is aimed at the advanced aquarist. Many of the products are improvements or spin offs from the original Seachem line. Salinity salt mix is no different. Seachem gaurantees that Salinity contains ”everything you want in a salt and nothing you don’t.” Using EPA Standard Method 6010 Salinty is guranteed to mix at:
- 8.8 pH
- 9.8 dkH
- 1265 ppm Magnesium
- 437 ppm Calcium
- 383 ppm Potassium
(Note: given the relatively low amounts we are assuming 1ppm = 1 mg/L)
The biggest question is at what salinity? At 1.025 Reef Salt has been mixing at 500ppm calcium, well above the 380-430 ppm that SeaChem lists for their 1.021-1.025 specific gravity range.
Salinity’s listed analysis shows 5ppm less Calcium than ReefSalt, but in both cases salinity / specific gravity measurements are not given by Seachem. Most interesting is the increase in heavy metals like Copper and Zince–two heavy metals that can increase coral coloration via toxicity and zooxanthellae expulsion. Reef salt previously listed Cu at 0.0003 and Zinc at 0.0107. Meanwhile Salinity shows over 150 times that for copper and 4 times that for Zinc. Cobalt is increased 200 times in Salinity as well.
These levels are elevated from NSW, which is not uncommon in synthetic salt mixes (No salt study is without debate… see Shimek Inland Salt Study). But it is interesting as that they are so different than the Seachem line of salt.
We’re hoping the early numbers are based on 1.025 specific gravity. We’re also hoping the clouding and elevated calcium issues we’ve been experiencing over the past couple buckets of Reef Salt are resolved. High hopes for Aquavitro’s Salinity Salt, can’t wait to try it.
