Low alkalinity Help please!

Hi Can anyone help please. We have a 15ft x 4ft pool (approx 4500 gal)and PH and chlorine levels are perfect and have been for a month, but, since filling pool I cannot get alkalinity up It is between 0 and 40. Can anyone advise me on how to increase this. I have looked at a couple of websites and they mention bicarbonate, does this mean bicarbonate of soda and how much should I use, and, do I put it straight in of dilute it. Any help would be appreciated. Thank you Pauline

You can use The Pool Calculator to figure out how much sodium bicarbonate to add. You can just use Arm & Hammer Baking Soda which may be less expensive than the Alkalinity Up from a pool store even though they are the identical chemical.
