Water Changes

[DashingAquatics]

How often should you do a partial water change? If I do one once a week my corals don't fully extend and or expand their pollyps, and two weeks is working for me is 1x every two weeks good enough?

in the past i have done 10% weekly with some tanks, and 20% bi-weekly, didnt really see any differences

I have been 20% weekly and all my corals stay open during and after. Whatcha got in there?

Does the new salt water temp match your tank?

 

Edit: I do 10% a week with no problems.

I do 10% every week. No problems with my tank after a change either.
