New tank mixed with old tank water

[OrangetheClownfish]

Is it possible to set up a 10 gallon saltwater tank and fill about a quarter of it with my current saltwater tank's water? My current tank is running stable about 5 months already, keeping a zoa colony, a blue leg hermit and a clownfish under 2 normal filters, no protein skimmers no water changes

Can i put some of that water in a new tank and add newly mixed water, and start keeping corals in it? am i asking for trouble in some sense?

Please help. The reason why I'm gonna start the 10 gal is for a BTA (it'll have a protein skimmer for it)

And i wanna put it in when the tank water is 6 months

Which, is the main question. if i mix 5 month water and newly mixed water does it still count as 5 month water?

No problem. Just be sure to transfer some biomedia from the mature tank to the new tank.

Juz need to make sure you are using the same salt and salinity.

Shouldn’t matter I think.
I just transfer the water from my 2ft to my 3ft and top up with new salt water last month.
Technically it’s like doing a water change.
Do have Corals and fishes in my 3ft now and they are looking quite well for a few weeks already.
Btw, I’m not a pro, so if mine survives, so should yours?
