i have an existing 110 gallon tall last night i went and bought a 150 gallon long i know the rite thing to do would use the existing live rock and water from the old tank and put it in the new tank and just replace the 40 gallons with ro water and more live rock . but heres the problem about 1 month ago i had treated the tank with copper safe i no bad thing to do. but i didnt no this at the time.so heres the question should i use new water in the new tank along with new live rock?right now its only live rock and fish but i might want to do a reef tank in the future.
