In other words, we really don't have any idea. Hot cars shouldn't affect stabilizer readings.

It looks like it's a plaster pool. If it is, you can go ahead and do this:

#1 - Test the pH and make sure it's in range (7.0 - 7.8)
#2 - Run the pump 24/7 (should already be doing that!)
#3 - Add 8 gallons of PLAIN 6% bleach to the pool.
#4 - Repeat the following evening.

That will be sufficient chlorine to clear up the algae even if the stabilizer is 100 ppm.

DO NOT DO THIS IF YOUR POOL IS VINYL!!

If your pool is vinyl, you MUST find out what your stabilizer level is.
