My 20 g tank is currently nearing the end of the 3rd week. I currently still have the 5 zebra danios and 2 cories. I haven't added any fish in the past 2 weeks. I performed my 2nd water change today and the stats are as follows..
ammonia .25, Nitrite a tad under .5 and Nitrate is at 20. The water change unly slightly lowered the nitrite and nitrate, while the the ammonia level has been consistent. The fish appear to be doing well. Any thoughts as to the progress of my tank?
