You could do daily water changes if you wanted. As long as everything matches. Temp, salinity, ph. Just dont want major fluctuations.
There has been instances i have done 50% daily for a week with no ill effects. I wouldn't recommend 50% tho. 10-20% will get you where you need to be.
Obviously the more often and greater volume pwc
will drop levels faster, but alone is not a remedy.
