Opened to a green mess. Bugs, worms (larvae?), algae, leaves, even a roof shingle. Bought a new k-2006. Started the SLAM process 2 weeks ago. Began removing all debris. Maintained slam level chlorine while brushing and backwashing 2X/day. Lost a brush head, lol, and had to buy a new one until we could see the bottom. We passed the OCLT this morning. Thank you TFP!
