Hello, I'm new to this forum and am hoping for some input. I hadn't cleaned my tank for quite a while and dug into it today. I kept noticing that
anywhere on my hand where there is a scrape or hangnail or whatever, I felt a "shock." I have had this before and figured it was just ammonia in the
water due to not cleaning it for a while. However, I became aware that while I was dumping fresh water in the tank from a bucket, if my thumb touched that
water, I felt the same sensation. I took the bucket away and stuck the same thumb in it and nothing happened, then when I started dumping in again, it
happened again. So..... I feel that something must be traveling up the stream of fresh water, from the aquarium water and causing the stinging sensation.
Anybody else experience this and what is it??
