The skimmer was surging and growling, and needed to be cleaned up. 20 minutes later, I vacuumed the detritus out of the skimmer section as it had built up quite a bit over the last six months (or more). Lastly, I cleaned off the screen to the Nero 5 pump, as well as the end panel of the frag tank. Things are more tidy. I’ll have to test the water tomorrow.
