Used the liquid formula 90, and its hard to get your mind around these crazy dilution rates, maybe we are so used to being ripped off with all the extra water/fillers added to pad these products out.
Also added to much and foam everywhere.
Only one thing I did not like was that loads of large hard cystals form in the bottom of the solution bottle, they did mix when added to hot water, but put me off the liquid.
Any one else had this problem?
