I have some in my cherry shrimp tank and its making me crazy. Noticed the hydra after a blow up of cyclop population. Ive been doing 20-30% water changes every other day and feeding my shrimp once every 3 days. I just want the f*3^ing hydra gone!!
What does that work out to in specific gravity do you know? I have hydra in my brackish tank and its thriving.salt is useful for the erradication of hydra at 0.3-0.5 % for five days. you'd have to remove the shrimp temporarily of course.
