Aside from being liquid in form, your septic tank safe laundry detergents should not contain (or at least have low amounts of) phosphates and surfactants, and should be biodegradable. Phosphates encourage algal growth. If algae grow too fast and too abundant in the water system to which the phosphates drain to, then there will be a total depletion of dissolved oxygen. Of course, when there is no oxygen, there is no life. The aquatic system is left for dead. Surfactants are the sud-producers and grime-lifters in the laundry detergents. The more surfactants, the more soap suds you have. Another trait that you should look for in your septic tank safe laundry detergents is that it should be concentrated. A concentrated liquid septic tank safe laundry detergent allows you to wash clothes even with just a small amount.
