water change on a blackish tank

[mark.]

just wondering how much water you guys change on your blackish tanks?
same as fw or less/more? thx

when I had brackish tanks I always did 50% water changes. I was keeping puffers though which are very messy fish and require larger water changes than most other fish. at the lfs I briefly worked at they changed around 1/3 of the water each week in all fresh and brackish water tanks.
