Was thinking this may be condensation. Since above ground pools are usually on the ground and we don't realize how much they do condensate I was just wondering. My pool is on 6 inches of concrete could this puddle on the low side of the concrete be a small leak or condensation? The puddle never really went away until it cooled off. It is back when it slightly warms up. We noted that the water still in pool has went down a little with the ice floating on top. Then the puddle has come back. If it is a leak, could chlorinated water freeze? Need to Know if I need to get another liner.

Katie, where do you live and what has the temperature done this winter? It is most likely a small leak but you can't do much this time of the year, depending on your answer to my question, back to you.
