:;saber When I mean bubbly water, I don't mean the kind you mix into your drinks... I did a pre-test before I cleaned my tank, and it all was good, then afer an hour or so of cleaning it out... then the water was all bubbly and the bubbles were sticking to my fish, their fins and gills, and then they started to float..... :''''''( - 6 fish, 1 snail :'( The NO2 and NO3 stayed the same, but the GH tripled, and the pH went up 2 points.... The water was all bubbly There was tons of slimy egg sacks, snail ones, as their is 1 little snail in my tank now..... They seemed to be everywhere once I filled my tank back up, and it made the whole thing once...... :-[???
