My tank is almost cycled. My ammonia and nitrites are going down, but my nitrates are still off the charts. Should I do a water change before I introduce new fishes to the tank. Help
YES DO A WATER CHANGE, BUT ONLY WHEN YOUR NITRITES AND AMMONIA ARE AT ZERO. I USUALLY DO A 25% WATER CHANGE AND LET STABLIZE FOR A WEEK BEFORE ADDING FISH. GOOD LUCK
