Mike,
I have followed the TFP pool care process for about 8 years. I have three pools, so that would be 24 "pool years".. In that time I have never had algae.
Once you get rid of your algae, if you follow our process, you will never get algae again.
As a moderator here, I often hesitate to answer SLAM questions, as in those 24 years, I have never had to perform a SLAM.
It is really just that simple.
I am also in the DFW area.
Thanks,
Jim R.
