As some of you know I've been working on establishing a SPS dominated 57g oceanic tank. After noticing whitening of some of my corals like I have never seen before I realized alkalinity was at 5 ad way to low. I began dosing to raise and brought it up to 6.5. After doing a water change I dropped back down to around 5 and decided to test the salt water I bought from beyond the reef. I discovered their water was at 5 Dkh. Wtf? Is this normal?
