i've been using sulphuric acid to lower the ph of my ro/di water.i bought a plastic container of sodium bisulfate and am going to mix up a stock solution of ro water and the s.bisulfate.does anyone have any idea how much i would want to add to a gal or liter of water.also any idea as to how much to add of the stock solution to a 55gal tank(ph 8.2 and hardness 16ppm)to bring it down to 5ph.i add just enough ro right to bring the hardness up to 40 to 50 ppm also.
