I use EvapoRust as well, and a tank made out of PVC pipe. The EvapoRust is usually fully spent and black after 48 hours, and while not prohibitively expensive, may not be the most cost effective solution. There are YouTube videos with formulas for homemade chelation agents with really cheap ingredients (even EvapoRust is 90%+ water, after all), but I am yet to test them.
