Not really look at Kent Marines web site it sets dGH. you need a buffer for carbonate hardness (Bicarbonate.)
Adding RO Right only adds electrolytes to the water. You need to control the PH and add a PH buffer. Kent marine who produce RO Right suggest their PH buffer but the natural PH buffer is sodium bicarbonate. There is a excellent android app called “ Fish Tank Hardness” that has all the calculations for RO Right bicarbonate and both dGH and dKH so you can add Ro right to achieve a desired TDS or add RO Right to achieve a desired hardness value. It calculates both. But be aware the buffer bicarbonate will slightly raise PH as well as acting as a buffer. I use this app and its so simple I’ve checked it against my TDS meter ad it is correct. I set my dGH and dKH and dont add any PH modifiers at all just change the water regularly. Most fish don't like big changes but can adapt to slow changes more than you may than you may think.
