Doing a deep clean of the DE filter and found this in the pipes, and was also all over the skimmer basket. Decently easy to scrub off with medium pressure. In the middle of my SLAM and close to the OCLT, but have been stuck at 1.5ppm to 2.5ppm loose every night still. DE filter was the last thing to clean and it looked bad. But saw this in the pipes and don’t know what it is.
What is this?

Seems to be some residual sludge or scum that accumulated over time. Not much you can do in the pipe in areas you can't reach, but shouldn't be an issue long-term. The elevated chlorine will do what it can during the SLAM Process.
