- The tank is a plastic holding tank, and was washed thoroughly before use
- The water is tap but has been treated with ammo lock.
- The salt is solar salt.
- salinity was proper.
- Temperature was a little low, but was still in range of water that the jellies were found in.
- Water affects snails, jellyfish and crabs alike.
Is it possibly the use of tap water? Any help would be greatly appreciated.
Also, here is some underwater footage of the jellies before they began to act up.
