My ammonia level was .5 in a tank that I tried to fishless. I was given the advice to drain it and refill it until I got 0.0ppm. Well I did it 3 times and before I drained it the 3rd time, the ammonia reading was .5ppm. I drained the water to 2" above the gravel (29g aquarium) and now I am filling it up.
Will that be safe for my fish to live in?
thank you all...
