When used regularly, SL-Aqua Magic powder ensures clean and stable water parameters that aide in keeping happy and healthy shrimp. SL-Aqua Magic Powder helps shrimp protect their digestive tract, aid in digestion, improve feeding efficiency, as well as increase the overall vitality of shrimp in an aquarium.
