So I had an algae problem a few weeks ago after going away for a few days. I treated it with liquid chlorine, following the slam process and it appeared as though the algae was gone. Also I have a salt water pool and but am currently chlorinating with liquid chlorine as I need a new swg. I had to buy a heater this year so I just can't afford the swg this year. Also, I don't have a Taylor test kit as they are hard to get a hold of in Canada at a reasonable price. I am testing with strips and my chlorine level is at or above recommended levels all the time over the last week. But still I am getting a very thin layer of green algae on the bottom every day. I'm not sure why this is happening. I am brushing and vaccuuming all the time. I have cleaned the filter numerous times and I am keeping my chlorine high. Again it is only a thin layer I am getting with light buildup around the seems.
