how much swing is supposed to be for 10% water change?
i have a total 40G system, i change 4 gallon IO water. i measured today using Salifert test kit. The pre WC was 9.3 (fairly stable for about a year already), post WC was 9.9dkh. Is that a big swing for SPS? will that have an impact to SPS? I have sps coloration challenge, i am thinking this could be the issue or one of them.
