...of the algae in the pool! One of my friends mentioned that her hubby always removes their ladder at the end of the swim season, and cleans it 'real good' at the start of the next season. That got me thinking...so this afternoon, I removed our ladder and had a look at the 'hidden' parts of the ladder. Oh, yeah! Algae galore! (Sounds like a Bond Girl name.) I was planning to start the cleaning, but the distant thunder I heard when I started thie project became a constant rumble, then great big raindrops were falling from the sky...I decided holding metal tools and working near a small body of water might not be in my best interests at the moment! But it looks like I have a project for tomorrow!
This is the 'front' of the ladder--the part easily accessible even while in the pool. See the bits of green under those edges? ALGAE!
This is the extension at the bottom of the ladder--where it adjusts to fit the depth needed...yeah, gotta clean that.
Here we have the 'back' of the ladder, the part closest to the pool wall. When you think about it, all those nooks and crannies make this a really bad design for a swimming pool ladder! 
And here is a closer look at one of the 'nooks.' Yeah, those things are history. Where's the bleach? 
As you can see, I definitely have a project ahead of me--I hope I remember to take photos before I put the silly thing back in the pool!
You'd think with all that green stuff growing there, the pool would be a mess. It is not--it looks great!
