When I tested my tank and everything was at 0 (ammonia, nitrite and nitrate) I decided to go and get a turbo snail to clean all the algae off the tank. I did the process of slowly adding my tank water to the lfs water in the bag to level out the levels for the snail then I put the snail in the tank. I then took my two clowns and put them back into the tank the same night. This morning when I checked my levels ph went up .1 and nitrate went from 0 to 20ppm. Is this from adding all three back to the tank at once?
