blocka Posted April 18, 2014 Report Share Posted April 18, 2014 As the title says what is the best way of raising the gh in my tank where I live I'm on rain water and the water is very soft under 100ppm I'd like to raise it to 200-300 what would be best to do this fish in the tank is a mangrove jack thanks Link to comment Share on other sites More sharing options...
Donny@ageofaquariums Posted April 18, 2014 Report Share Posted April 18, 2014 Add some marine salt to the water. eg make it brackish. Good marine salt is high in calcium and magnesium. GH is a measurement of the amount of disolved calcium and magnesium in water. Link to comment Share on other sites More sharing options...

Donny@ageofaquariums Posted April 19, 2014 Report Share Posted April 19, 2014 Standard sea salt sold for human consumption is sodium chloride. Therefor it will not effect GH. Epsom salt is magnesium sulfate, so adding it will raise the magnesium. Therefor it will raise GH. Coral is calcium carbonate, so as it disolves it will raise the calcium. Therefor it will raise the GH (and the KH, as the KH is carbonates.) Adding proper marine salt, such as that used for marine aquariums, is the best solution IMHO as it raises GH, KH, salinity AND it raises them in the correct proportion.

Sclero p Posted April 20, 2014 Report Share Posted April 20, 2014 If you have room in your sump a mix of coral, oyster shells, and crushed limestone. Best limestone to use has dolomite, Calcium carbonate and Magnesium carbonate together. Sure I have posted this before somewhere. Pic of a drum set up for a pond not in use atm, crushed coral in bottom dolomite limestone in middle and oyster shells at the top easy to set up a sump chamber like this.

blocka Posted April 20, 2014 Author Report Share Posted April 20, 2014 No room left in the sump at the moment but I'll look into making a 6ft sump when I can find a suitable tank Link to comment Share on other sites More sharing options...
Sclero p Posted April 20, 2014 Report Share Posted April 20, 2014 Our local Moreton limestone deposits have a high percentage of magnesium carbonate.................. Link to comment Share on other sites More sharing options...
