Yeah the preds are pricey, way pricey and then the best way is to keep them alive in the container and in 2 weeks release the rest so its kinda done in shifts. I heard nothing but good things but still I dont know how they get all the mites and they still recommend you bathe the crabs too (Julia crabs article Mites friend or foe at CSJ)......too much darn work. I came close to having an infest with a crab I did not ISO and that is why I wont cheat anymore......
