I have tried Pottasium, aminos, iodine and strontium in the past and never noticed a diffrence. However did not do it more then a month so not sure if that was a good amount of time to see benfits. I have done DT's for a few months last year and noticed an increase in feather dusters, pods and sponges. It was to expensive to keep doing it and did not want the hassle of making my own so I quit.
