Had a good soaking rain early this morning, just checked the water chemistry
ammonia = 0 ppm
nitrite = between 0 and 0.25 ppm (closer to 0.25 ppm)
nitrate = 40 ppm
hardness (GH) = 75 ppm
chlorine = 0 ppm
alkalinity (KH) = 40 ppm
salt = 0.11%
ph = between 7.0 and 7.5 (closer to 7.5)
temp = 75 F
It appears a have a very slightly higher nitrite compared to yesterday morning (when I measured zero), I have seen before (might be related to rain/runoff) but fish seem unchanged in behavior, and becuase it is so low, don't think it is a concern.
One other thing to add to the thread is that only once before have a seen a similar observation: about a month ago I had my shows with a spot on his pectoral fin...I had a koi vet come check him out, didn't see anything on the scrape, and he suggested that I treat the koi in my sick pond every other day for three cycles with an antiboitic and he cleared right up. I might try the same approach with my shiro if i don't see anything on the scrape.
Here is a pic of the showa's old fin spot (now gone, don't see any trace of it)...
