Adron Posted Tuesday at 08:47 PM Share Posted Tuesday at 08:47 PM Hi friends! I just started the Co-Op's recommended med trio treatment yesterday in a 20-gallon with a relatively young nitro cycle going in it, but a fair number of plants. This morning I saw a red spot on one of my new guppies' tail, and it looks sort of 3D, like a growth or something hanging onto the tailfin. The internet said "red spots bad! ammonia spike!" and I panicked, about to abort the whole med process and water change the heck out of the tank, but first I tested my water, and ammonia looks to be near zero. Nitrites zero, and nitrates near zero as well. pH and KH however, are quite a bit lower than I'd like - KH is ~ 20 ppm, and pH is ~ 6.2-6.4ish. GH is high; ~100-120 ppm. Since it doesn't appear to be an ammonia spike, does my low pH buffering capacity have something to do with it? Or is this red spot a predictable response to the med trio treatment? Like, is it some kind of evidence of parasites leaving the body? Or is that wishful thinking? I've thrown some API Stress Coat in there to try and raise the vibes in the tank, and I'm trying to take pause before freaking out and aborting the medication mission with water changes. But could use the advice of this wizened community! Thanks so much. Link to comment Share on other sites More sharing options...
