I have a fluval 305 cannister on my 46g. Every couple of weeks I clean out the foam filters and just make sure everything is clean. I notice when I am rinsing out the foam filter pads that afterwards I get a stinging sensation in my hands for a few hours. It's almost like there are tiny splinters in my hand and when I rub one it stings the living daylights out of me. But, there is nothing visible on my hand. Anyone have this happen to them, and what is it?
