I had a problem with my green finger coral so i barrowed my friends test kit and my nitrate was at 60 so I did a 13 gallon water change(I have a 55 gal) and the nitrate went down about to low side of 40. I was wondering how much of a water change is to much? I know u shouldnt do more than 50% but weekly can I do 25% till my nitrate is gone? Thanks any help would be great.
