Alright, my fish are shipped and will be here soon! I just had a few last questions regarding the quarantine tank and the sponge filter. I've never used a quarantine tank, so I'm a little nervous. So, for background, about a month ago I set up my new tank and started to cycle it. It went through the nitrogen cycle and grew lots of algae, and my plants are growing like crazy. I added some cherry shrimp a couple weeks ago, and they are fat and sassy- doing well. One even molted yesterday! The water is holding up with consistent readings for the past couple weeks- it's perfect. Ammonia 0 Nitrite 0 Nitrate 25 (I have plants and have been using Easy Green- hence the nitrates). Anyways- about 3 weeks ago I added a small sponge filter to use in future quarantine tanks. My water responded positively to this new addition and got much better readings very quickly. My question is this: will this little filter have enough bacteria on it after 3 weeks? I'm a little nervous as I worked so hard to get my tank to where it is now, but it would be sad if my QT wasn't quite right, and I lost some fish. Would it be okay to squish my main filter sponge in the QT water to add more bacteria?
