Will this work out cheaper than just buying the All-for-reef liquid?You can take 140 g of Carbocalcium Powder fill it up with R/O water to 800 ml and dissolve as much as can be dissolved. Then add 100 ml of each, A- and K+ Elements, and dissolve the remaining Carbocalcium Powder completely. At last add 12 g of Bio-Magnesium and dissolve it. This solution comes closest to our All-For-Reef and will add all major, minor and trace elements necessary for good coral growth.
Of course you can also premix 140 g of Carbocalcium Powder and 12 g of Bio-Magnesium.
The 12 g is an empiric quantity. We added more Bio-Magnesium at first and noticed increasing magnesium concentrations in the tanks. So we reduced the magnesium concentration. However magnesium consumption may vary for example with coralline algal growth.
I also noticed it quite hard to get carbocalcium powder in the uk and costs a fortune to ship it from Germany.
