I've just done the stupidest thing ever. I bought a new spray bottle for my tank. Filled the old one with water and a bit of washing up liquid (i use this to put on windowscreen backgrounds for my tanks). They're both green which was a very poor choice in hindsight. I accidentally sprayed the tank with the washing up liquid bottle and not the water. I pumped it once or twice before i realised my mistake. It's a seasoned bioactive tank, I have one frog in there, What do I do???
