I used it just like the directions stated, and it took almost all day for the fumes to fully clear. Also, why did you spray the bare cage? The directions make it clear to NOT do that?

Empty tank, wash it down really good, dray it out, put substrate in, spray it down like it says, and wait till you cant smell it anymore, I was sticking my head in his tank and taking huge wiffs of air, if i smelled any PAM, I let it sit more, took almost all day befor all I smelled was the aspen. Put everything back in, and rock'n'roll.
