Reef/marine aquarium cycle, the right way!!

Don’t use actual live rock, ever!!
It can introduce hitch hikers you do not want in your tank. If you go with corals as such, you will get enough of them anyway!
To start a marine tank, with just fish and mobile inverts like shrimp anemones and so on.
Anems will most likely bleach due to what is in your tap water, but if your tank is matured fast and really well and you feed your anems, they don’t care!! You can always use neutralised tap water sat in the sun for a couple of days no worries, the sun helps settle out metals and those sort if things, just don’t use the very bottom water of that bucket or what ever if you do it that way.
You can go with made up water, but when starting a marine tank, always set up your base rock/structure as a nice set up you are happy with, all the system should be complete, add what ever water you are using to fill your tank and if you are using anything like a canister or sump, the external bio system all filled as well!
Never neutralise your tank water in the tank and mix, if there are any chloramines as in ammonia bound with chlorine like here in auses water, the salt added will stop the bond being broken and you will end up with an ammonia lock and you will have to start again!
To get a cycle going well, get some marine life meats in a bucket some where away from the hose if need be with an air stone putrefying that meat, in 6 to 9 days it obviously stinks, but those varied natural ammonias are a great tank start.
Tanks running, add a few cups of water from the shops tanks or another reefers tank with in two hours of extraction, this has the bacteria in it that begins it tall, the pore that putrid water through some material like and old towel to filter out the particles, then add that water to your system.
Now get a bit of rock from the shop or another’s tank, not much, just one fist size or what ever sized piece of rock that been in there for ages or a cup of sand from another tank, pour it in.
Begin testing for nitrites from day 2 and on till those nitrites are virtually zero, then add a little marine meats to really mature your bio media. You see its not just bacteria that runs matured marine tanks, its protists as well. Two weeks from near zero nitrites with on going marine meats in there and once nitrites do not go up anymore and remain on zero, your tank is matured!!!!
