Looks like you are on the right track. I suspect it will still ne another week or two before you should slowly begin to add fish. You need to be able to process up to 4ppm of ammonia through the stage to nitrates in 24 hours. Then you may be sure your cycle is complete. I typically use pure ammonia for a fishless cycle (ACE Hardware has some) and ramp my ammonia up to 4ppm and keep it there. When the daily test shows zero ammonia I add another 4ppm and see if it cycles through to 0 ammonia and 0 nitrites in 24 hours. If you do the ammonia make sure it's pure and doesn't have anything else in it but ammonia. Good luck. What type of fish are you thinking of getting?
What size is the tank? Just curious because if it is small, you may not want to add the two clowns first as this could cause a jump in ammonia/nitrites while your tank is still stabilizing. That being said, they are pretty hardy.
