I swear, things like this only happen to me lol. I was calibrating my PH probe for my apex. I had the solution package open, sitting in a glass so I wouldn't knock it over. My 2yr old decides he wanted to knock it over. So I was able to grab it and keep about half of it out of the tank but some definitely went in. How screwed am I? Running carbon now but I don't have gfo..
