Possibly lost my white spotted sharpnose puffer and a possible 3 other puffers in this mess. IDK what happend the only thing i can think of is the micron filter i have was not rinsed well enough after being in bleach water for cleaning....my PH was SUPER LOW, Like reddish / light reddish in color, not even on my chart! Fish are looking terrible right now. I added PH buffer and im heating some reef water i had on hand to ready it for a water change but what else can i do here???? All other level are normal but my PH is dropped off the charts, after testing now its at what looks like 8.3/8.4 but i dont think that the buffer has totally set in....IDK...PLEASE HELP ME KEEP MY FISH!
