Hey guys so recently I have been fooling around and adding plants in my 35 gallon tank, recently however I went to test the water and noticed that both nitrite and nitrate levels are very high but ammonia remains at 0. I've been doing water changes in an attempt to bring these levels down but so far it's not working, I've even added a new filter with Fluval's biomax media in an attempt to allow my BB to grow and deal with this spike. The only thing that has changed in my tank that I can think of is the addition of Flourish Excel as well as root tabs. If anyone has any idea how this happened or any suggestions how to fix this I would be very grateful!!
