Water change during fishless cycle
I am in my second week of cycling my new 20G right now, I have added a lot of plants to the tank 4-5 days ago and have not done any water change since. I test my water daily and my ammonia and nitrite level has been pretty steady (both at around 0.5PPM).
How often I should do water change during the cycling? There are two concerns I have here, 1. keeping the plants alive and let them adjust to the new environment and thrive, 2. doing water change will lower my nitrite level, and will this affect the grow of the batericia (ammonia level will not change since my tap water have about 0.5 PPM on ammonia in it). I have seem very little nitrate in my tank so far, so I am not sure if I have any bacteria converting the nitrite to nitrate yet, or just simply my plants taking up all the nitrate. However, my ammonia and nitrite level been pretty constant at 0.5 PPM.
Also, I use fuval cycle to help me kick start the cycle, so far I add the recommended amount daily to my tank, and my question is, does it actually contain any good bacteria? How they keep these bacteria alive in a bottle? Does it contain any ammonia and nitrite? I suspected that the nitrite in my tank so far are from this fuval cycle since I started to see nitrite reading a few days after i start adding this stuff. The main reason for this is both the ammonia and nitrite level are always around 0.5 PPM for the past week, it never go up or down.
