hey guys i just got a new tank i don't want hard calcium to make it look bad like my ol tank. i always use cold water. alfer a few weeks white bits of calcium begin to biuld up on the tank, filter and heater. is there any fish friendly chemical i can use to dissolve these chemical like alot of you MFK's use (If i'm right). I want my tank to be in mint condition for a long time. Is the reason why alot of you MFK's hhave calcium free tank is beacuse you guys use solf water?? IDK. i you guys give me advice???
