raising gH in tank

[mincedmeat]

how do you possibly raise gH without affecting your pH and kH levels? i suppose adding coral stones might help but what if your pH is already at the level that you require? besides chemical methods, are there any other way/method of this?

you can try mosura mineral plus..

This products does not alter the pH and kH of your water, but will mildly alter the tank's GH value and increase TDS.
