I just join this website last week because I have not been able to get rid of my algae problem. Yesterday I woke up to my pump sucking air because the water level dropped so much over night it no longer reached the skimmer. This pool is one thing after another, I have not even completed my SLAM yet. I did the bucket test and same thing happen last night, water dropped and the bucket comfirmed that. Since its above ground pool, I can see all of the plumbing and there are no wet spots around the pump so that leads me to believe its the linear. I've read the Pool School on Pool Leaks but it just seem impossible to go around this entire pool with food coloring to find the leak. Would I be able to spot a tear in my linear? Or is it more than likely at a connection point? Help Please!!!
