Water change question

[josh88997766]

Im going to be doing a water change soon it’s my first ever saltwater tank 10g gonna change 1-2 gallons for do I mix salt water to the salinity of the tank I know I might sound dumb but I wanted to maker sure also if I change like a gallon do I really need to make sure the water is close to the tank obviously wouldn’t make it too hot or too cold but do I need to stress out about temp thanks

Temp not critical, make sure to match salinity.

As long as it’s not too far off. More of the case when you have sensitive corals. You would like to get temp lined up not to shock anything

Close yes, like within 10 degrees. Closer is better though, but dont stress it being matched exactly. The lagrer the water change the more important that becomes though.
