I have recently set up a new tank. after a couple of days i added a few fish. as its a new tank when do i start to clean it. ive tested the water and my ammonia levels are starting to build. i guess this is the start of biological filtering. do i do a water change and clean my filter sponges or just leave it. Please Help! 

It is risky to the fish if you don't know what you are doing (mind, it's risky if you do know what you are doing
), so you need to get clued up fast
I'd start with [topic="224306"]this thread[/topic] that explains how to fish-in cycle, so that you fully understand the process and how to go about helping it along
After that, look through the articles [topic="88643"]here[/topic] to learn more about rutien maintanance and how to carry it out
to TFF BTW
