Water has very high alk levels according to red sea test It reads 3.6 milli equaivalents per liter strait out of my rodi how can i lower my alkalinity in my rodi water it also reads the same strait out of the sink .Thanks everyone.
I would check the alk of your tank water and your pre-made salt water, your ro-di shouldnt matter, your tank water will adjust the alk in the water you are adding and your pre-made water from changes should also be adjusted when you mix in the salt.....
