sparklymoonshrimp Posted July 6, 2021 Share Posted July 6, 2021 (edited) Hello Everyone, I started trying to cycle my second aquarium, which is a 5.5g with two of the Aquarium Co-Op nano sponge filters (cycling two sponges so I can downsize a sponge filter in my other aquarium), on 04/24/21 but as of right now, over two months later, the parameters are sitting at: Ammonia = 5.0ppm, Nitrites = 0.25ppm, and Nitrates = 0ppm. I was able to detect nitrites starting in mid-May, but the concentration has literally sat unchanged as well as the concentrations for Ammonia and of course Nitrate. The only difference I can think of between cycling this tank and cycling my last one is that the last time I tried cycling an aquarium, I had a shrimp/planted tank substrate so perhaps that gave more porous surfaces for bacteria to grow on. I didn't think that would be necessary though, especially with an extra sponge that could help nitrite colonize, but I'm wondering if it's maybe due to my area's very hard water? Please help if you can! I'm anxious to get my next aquarium going. 😭 Edited July 6, 2021 by sparklymoonshrimp Link to comment Share on other sites More sharing options...
