some people do them once a month some do it bi weekly and others do it weekly which is the best. it is recommended to change 5-10% for weekly. and just playin around with the numbers i would say 10-15% for bi weekly and no more then 25% for the monthly

Nope, salt has trace elements that are pulled out by corals and the skimmer so it can't be re-used.


I used to feel the same way about 10% water changes weekly till about a year ago my tank has never looked better and i do not have to spend all that money on additives.
