I asked before what your water was like when you tested it have you done so?
Depending what the red spot is I would be keeping it divided in the 300 and doing good water changes on the 300 and adding salt to the tank. Not directly pouring it in but dissolving the salt in water then adding it to the tank. What filtration do you have on the 300?
