Hello! Just wanted to confirm that this is ich? The yellow tangs spots lasted for about 2 days and is now completely clean of spots and looks very healthy, wrasse still has maybe 1 spot (had about 10) added some coral a couple weeks ago…. I did add a little baking soda / mixed RODI to the water to raise my alkalinity a little bit if that could have caused the spots? Dropped my ph from 8.1- 7.9 (checked with a Hanna so not very accurate) spots were on about 2 other fish minimally the next morning after I did that….. thanks in advance!!! Oh and my alk was 6.8 raised it to 7.5 in about a 24 hr period
