I am moving my 125 gal freshwater tank with 12 inch Jaguar cichlid. I am moving from well water to tap water. Do I have to move all the water or can I use some of the new tap water and add the conditioner. Iam new to this so I can use all the suggestions I can get. I am only going to be traveling about 1hour, so will the fish be ok with no aeration? Thanks for any advice.
