i have the capacity to do waterchanges in the order of 30% very easily. is such a high volume change a good idea? total volume @250 gal and using nsw thanks

1.020 -1.025,anywhere in this range will work ok but the critical issue is stability.even a change from 1.020-1.021 in 24 hrs can stress your fish alot,keep it steady and adjust slowly.i keep my tank at 1.025 which seems common with more modern thinking.1030 pm here in nz...
