Well. I feel like an idiot. I was using a fish-less ammonia cycle to get my new 20g tank ready & I looked all over town for a bottle of ammonia that was unscented & uncolored. I didn't even think about it containing a surfactant! Now I have a tank full of bubbly, toxic ammonia soup! The surfactant has caused massive amounts of bubbles on the surface, which I have been skimming off regularly, and I dont think any bacteria can grow in that stuff. It would be great if I knew how to neutralize the sudsy stuff without starting all over, but I'm not extremely confident that is possible. I'm not sure how this will turn out yet, but I sure learned my lesson!
