Hi all, I just joined TFP after a 3rd year of my Intex pool turning green once the water temp got to about 95F. Today I went out and see that there are backswimmers in the pool as well. sigh... So, using the pool calculator I added 182 oz of bleach to get it up to shock level (7500gal) and I am ordering a TF100 to properly test.
Now that I joined, I donated to be a supporter and am wondering how I can get the $10 off of the TF100. Can anyone tell me how this is done?
