I am having no luck with my numbers lowering. I have no fish in there only a sponge filter and a heater thats set up to 84. Ive been cycling for over a month now. My nitrates have been super high for about 2 weeks now. Doesnt seem like my nitrites are lowering either (they dropped a bunch within the past 3 weeks as it was super purple but since then nothing), if they are lowering I cannot tell & im dosing ammonia every time it drops to 0, adding just a bit for it to reach around 1ppm or slightly over. Top picture is today Bottom is over 2 weeks ago.
