HELP we have got a problem!
So i did a total rearrange of my aquarium last night and setup a new aquascape, as well as a 50 percent water change and i changed the diy c02 and also added my ferts. This morning i woke up and all the fish were floating! Even the SNAILS! What the heck went wrong? I know it wasnt chlorine or chloramines because i added the stuff to remove them, and i did a nitrite test and my nitrites were through the roof. I did a 25% water change and i hooked up air pumps and ran the bubble tubes and it seems to be helping considerably, but im just curious at what did this in the first place? Ammonia spike? And when can i expect it to dissipate? Thanks...
