Slime behind Niche Light

[selectstar]

It's going well. I have all but completely converted over to BBB with SWG. So far so good.

The water seems cleaner and more polished than ever. I know my CYA is still high so I am keeping my chlorine a little higher than I normally would at about 7-8ppm.

I found that my ladder was also harboring some of the black mold/bacteria (or whatever it was) due to poor circulation. I have since drilled a couple small holes at the top and bottom of each rail with the thought that this may help circulate the water to the interior as people climb out of the pool.

Going forward, I will be more proactive with my light and remove it from time to time for cleaning. I've actually toyed with the idea of injecting straight bleach in the small circulation holes periodically to try and stay a step ahead this time.

Thanks for all the advice, that was the nastiest water/crud that I have ever encountered.

I suspect that, if you can succeed in fully eradicating it, you won't experience problems going forward, due to your more consistent and educated approach to chlorination.
