new tank, seeded sponge and media
I just started a new 10 gallon. Sand substrate, there is about 10 plants added. It has a sponge filter in it that I set up in my 20 gallon to get bacteria to grow on it for about a month. I also have 2 small bags of ceramic media that I put into my hangon back filters for about 6 months from same 20 resting on the sponges in new tank. One Betta and some snails, after a week, Ammonia is 0, Nitrite 0, and Nitrates 5ppm. How long should I leave the ceramic media resting on the sponge before I remove them.
