Newby here... how much of each do I need to add? We just emptied and painted our IG pool, at the home we bought last fall. Time to add water. We have a natural spring fed creek that runs by the property and we are filling the pool via a submersible pump/bucket system. (This is how the previous owner did it) It has only been a few hours and we are 2/3rds done. Now to start on the chemicals ... I used the pool calculator, using 0 as the start amount for FC, using their goal of 4, it says I need 300 oz. for the pool. That doesn't seem like much! I figured I'd need a truckload! So is this correct? If so, will go with their numbers, and see what test kit says.
