We recently experienced soma algae issues that left stains on the bottom of the pool. Does anyone have a technique to remove the stains. I've tried brushing which helps, but doesn't completely remove the stains.
Welcome to TFP! If the stains are organic, then usually increasing and maintaining the FC level a little higher, coupled with consistent scrubbing, helps. You can test that theory by carefully rubbing a chlorine tablet around in the area and watching for changes. Do you have a TF-100 or Taylor K-2006C test to share a full set of test results to be sure? FYI - Here at TFP we follow the SLAM Process to ensure algae is killed and removed.
