The new formula of LIVING REEF SPS SALT is specially developed for the growth and keeping of SPS (Hard Coral). Specially formulated with SPS required levels of calcium (Ca), magnesium (Mg), alkalinity (KH), strontium (Sr) and other essential trace elements of natural sea water to ensure optimum growth and color.
Only pure high grade raw materials are used in the making of LIVING REEF SPS SALT. Manufactured under strict quality assurance. Dissolves rapidly in Reverse Osmosis water to produce a very clear and high quality salt mix which can be used immediately.
Mix 35 grams of LIVING REEF SPS SALT per 1 liter of Reverse Osmosis water. Stir well until completely dissolved in the water. Check salinity prior to placing in your aquarium. Can be used immediately.
20kgs of Living Reef SPS Salt makes up 570 liters.
Calcium – 450ppm
Alkalinity/KH – 10dKH
Magnesium – 1480ppm
Trace elements at balanced levels.
Phosphate – 0
Nitrate – 0
@ specific gravity 1.026
This salt has been manufactured and researched for the last 15 years. It is now used extensively throughout Europe and around the world. After Living Reef’s extensive research on this salt and backed by the many positive reviews it gave Living Reef the confidence to put their name on it.
Adding to the range of synthetic salt mixes already available to UK hobbyists, This SPS Salt Mix is a new offering where internationally it is already stated to be used widely and with success by public aquaria. With this pedigree in mind, we were interested to get our hands on a batch and take our own readings. To be honest it took some effort to put any preconceptions out of our minds and focus on the actual product rather than the brand which we think perhaps isn’t as known or trusted as some of the more established brands here in the UK.
So, once we’d given the bucket a good roll and tumble and worked out how to open it (which wasn’t initially obvious), we set to work on creating a batch to run our tests. For this purpose we used freshly produced RO/DI water with a TDS reading of 000. Using a clean bucket, we brought exactly 20 litres of water up to 76f and then slowly poured in 700 grams (20 x 35g) of the salt (measured using calibrated electronic scales). Mixing was achieved using a 5000lph stream pump. After 3 hours, using a DI-calibrated Vertex RF1 Refractometer, we noted that the Salinity measured spot-on 35ppt.
Leaving the batch overnight we remeasured the Salinity the next day and found it unchanged. As a result we’d suggest that the mix stabilised quickly and, in addition to good clarity, no residue appeared to be left at the bottom of the bucket. We then proceeded to test the batch and our results are as shown below.
pH – 8.02 (freshly calibrated TMC V2 monitor – small sample shaken vigorously for 2 minutes before reading)
Calcium – 450ppm (Red Sea Calcium Pro Kit)
Alkalinity/KH – 8.5dKH (Hanna Test KH Checker), 10dKH with Salifert test kit
Magnesium – 1350ppm (Red Sea Pro Kit), 1480ppm with Salifert test kit
Ammonia, Nitrite, Nitrate – zero (Red Sea Pro Kits, Hanna HI83203)
Phosphate – 0.03ppm (Hanna Test Phosphorous ULR Checker)
Iron – 0.05ppm (Red Sea Reef Colours Pro Test Kits)
Iodine – 0.03ppm (Red Sea Reef Colours Pro Test Kits)
Potassium – 390ppm (Red Sea Reef Colours Pro Test Kits)
Looking at our results it’s clear that all the major parameters are within suitable ranges and therefore we’d have no hestitation in recommending the salt based on our initial observations. As a caveat, it’s always worth considering that testing is subject to variables of course, no matter how fastidious it is done. Overall though we do notice that our results correlate with those seen by others who have analysed this brand. One thing to remember is that that if you are using a ‘saltwater’ (rather than a ‘seawater’) refractometer you should aim for a Salinity of 38ppt and this is likely to increase readings slightly.
