I've never known what this standpipe is a couple feet from the skimmer. It's a valve box that always has (somewhat dirty) water and a standpipe that leads to an open return port.
I also can't find a way to remove my return jets to clean or adjust. It looks like there may be a special tool with two slots? Same for my fiber optic lights, which have 4 slots. I want to clean them since I have mustard algae.
Does anyone have a solution for keeping the vac hose from getting stuck on an in-water rock feature? I usually just leave the vac in permanently but it does often get stuck when the hose gets between this rock and the wall.
