We've been SLAMing following the guidelines for about a week now. We have not seen any real improvement in the testing since the beginning. When the pool was first opened, we had high CC and the FC was being eaten up quickly. It took a positive turn after a short time with SLAM (1-2 days). However, since then, we have been holding firm at about FC of 12.5 or so. The water also looks very clear. Is there something else that might be going on? The bottom of the deep end has some staining that I'm unsure of, it looks to be from the previous owners.
