I am new to pool care, we have a 16x42 quick set pool. Thanks to the info on this site all is well, the water is clean and clear, the numbers are in the normal range (oh, and 3800 gallons). My question is this, how much borax needs to be added in a pool my size in order to change the feel? The ph is in the normal range (7.4) it would be really only for feel. Then how will it affect the ph?
