a few months ago i purchased a 155 tank set up with 200 pounds of life rock and about 15 fish during the transport about 4 fish didnt make it and was left with the worst headache i could have imagined i was told if i used the same water there was no need to cycle the tank and 5 months after i am still buying salt and buying 0 tds water like its going out of style i have heard every solution told to man my last option at this time is put my remaining fish in hospital tanks and dry out the rock and cycle tank from scratch but my corals might not make it so i am asking anyone who might have had this problem to please help... thanks in advance.
