After setting up my tank I got the expected ammonia spike (initially it went to .5 ppm
) and within three days was not detectable. The problem Im having is that the nitrites dont want to come down. Ive been doing twice weekly 25%-50% water changes to keep nitrites below 2ppm. Ive been detecting steadily increasing nitrates for about a week now from just a trace to about 7ppm today. After each water change the nitrite levels fall, but slowly build back up. Im thinking that some maintenance activitiy Im performing is causing the nitrabacter to die off, or fail to flourish.
The set up is a 29 gal FW
tank, current occupants 2 black skirt tetras, 3 colombian tetras and 3 buneas Aries Tetras and several small plants. Im feeding twice a day mornings with small amounts of blood worms or tubiflex worms and evenings with flake, just enough both times that the fish eat everything within two to three minutes. Filter is an Emperor 280 with a factory cartridge and diamond blend (activated carbon and ammonia absorbant) in the loose media carrier. The tank is equipped with a 20 flourescent tube (shortly this will be upgraded to 110 watt PC
injection and a 150 watt heater, temp is 80 degress. The water is very soft IMO
, about 2 degrees KH
, PH is a stable 7.0
Not sure if Im doing things right or not, but I hate to let the nitrite levesl get too high. Sorry for the long post, just not real confident in what Im doing yet and I want to make sure you guys have the information you need to help me out if ya can.
Thanks a ton
