    A little green above the water level.

    There a couple of spots on the wall of my pool that gets direct sunlight for a good portion of the day, and I'm noticing some green tint in the grout, but it's above the water level line. How do I manage this and keep it from spreading into the pool? That's the only green the pool's seen in 6 months! Is this common?

    I'll let someone more knowledgeable answer whether it's common or not.

    You can always spray some bleach on it and scrub with an old toothbrush, then rinse with pool water. That should remove it.

    Maybe also post a full set of test results for us to look at. How does the water look overall?

    Yep, good plan. We get a little of that under the waterfall sometimes.

    I have an above ground pool and have to clean under the lip each year. I just walk around and spray with 50/50 bleach water then walk around with a brush then spray it all down with the hose. Good to go for another year.

    Once in a while I get some green right above the water line on the grout inside the skimmer throat. I just brush it off and raise the water level an extra half inch or so.

    Looks like I need to get some bleach and elbow grease and get to work! Thanks!
