GFO would help the Phosphate, Silicate and copper levels already in the tank. Also measure your RO output before DI to verify the membrane is ok (10-18ppm should be ok). Then measure your DI output and see if your total output is below 2-3 ppm.
For Borate you could just leave it unless if you are having pH swings. If you decide to tinker with it you could add 1t 20 Mule Team Borax to a qt of RO/DI and pour it in the sump. Test it first by mixing some in a cup to verify there are no foams or perfumes. The version sold in U.S. is usually fine; alternatively in your next water change you could include 5gal SeaChem salt mix to your normal salt mix.
