Water change

[Jeter22]

I have a 55 gallon saltwater tank, fish only. I change 10% of the water once a week. When I do the water change I take out all rock & decorations. I will do this for each half of the tank every other week. Do I need to keep this practice up or am I able to take out only water for the water change every third week?

I dont think there's any need to take out rock etc. I never do that.. especially now I have coral. Make sure your setup and aquascape allows for good circulation so you dont have to do that. I change about 20-40% of my water a month, and only change the water. Dont make it harder than it needs to be
