Setting up my used fresh water tank to marine

[FaDs]

Good day to all.. I am just bought a used 4x2x2 tank with sump. This tank already used for freshwater previously with some biofilter too. Wanna need some advice from you guys whether should i put the tap water and bleach and run the water cycle for 1 week..? Cause i read some reefer that some of them just pour the bleach to sterilize disinfect and kill all germs inside.

IMO if it wasn’t previously a saltwater system, bleaching is unnecessary. Perhaps just rinse the whole system with tap water with dechlorinator and then drain it before starting your system up proper starting the cycle
