anysia | With the heat comes a headache?

Was outside taking off crumbling pool cover (the Aussie sun pretty much toasted the one I got last year, turning it brittle) and noticed that rain water had managed to leak in. There was a bit of green on the bottom. 1.5 liters of cheap household bleach, hosing out of the filters in the pump, and using the gadget I rigged to vacuum the bottom. It's looking pretty good, still needs a bit more bottom vacuuming.

When I started watering the potted plant I started getting a twinge, then it decided to whether or not to become full blown headache possibly a migraine. *sigh* I decided not.
