Sulawesi 8,5 Minerals and Trace Elements Cardinal Shrimp Tank (230g)

This is good for making sure your shrimp grow a healthy and strong shell and get the nutrients they need

Fell hook, line & sinker for the online marketing behind this product. It appears to be mostly calcium carbonate. In nature, it would be limestone or crushed shells in the substrate or walls of the body of water. As acidity increases, it dissolves to buffer the pH. Making acidic water by passing CO2 into the water to force this to dissolve as the company suggests is therefore completely illogical. If you don't, then what you are left with is a cloudy mess. Much better to just use aragonite sand & then dose trace minerals like Iron or Magnesium. Live and learn.

I used it, and it seems to help my Sulawesi cardinal shrimps. However, it is tricky for mixing since the instruction calls for a “heaped” spoon during mixing so it’s kind of hard to know exactly how much. For that, I ended up using a weight scale and come up with a mixture ratio of 1 lb RO water for every 0.07 grams of this mineral. It’s something like this:1 lb RO/0.07 g mineralsYou can use a carbonated water maker like SodaStream to thoroughly mix these hard-to-dissolve minerals. For example and in my case, I would use 2.68 gallon RO water and pour it in a bucket with a water pump to mix/circulate the water; carbonate 1.32 gallons of RO water and pour it into the mixing bucket, then use 1 gallon of fresh RO water to reduce/adjust the water to a proper TDS of around 115-140 TDS like what Marks Shrimp Tanks has shown. This is basically the best method to mix these hard-to-dissolve minerals, and it’s all thanks to Marks Shrimp Tanks.- Yong
