SALTWATER EXPERT NEEDED?

I got a 29 gallon tank and set it up as a saltwater. I did this to get used to it, in hopes that oneday I will get a reef aquiarium. when i got it, the water solinity was 1.022, I checked for ammonia, pH, Nitrate, and all that good stuff. Everything was good. I let it run for a week( I know its supposed to be longer). I then added two damsels for a test run. They did fine so i then added a full sized clownfish, and a starfish. They did fine and i added a puffer and one other kind of fish that cant float so it sits on the liverock. So my tank is like this-29 gallon with lots of liverock, bacteria live sand, good filter, one clownfish, one pufferfish that grows 4 inches, one starfish, two damsels, and the non floating fish. Today i went to check the ammonia. I realized when i first checked it, i did it wrong. Come to find out there was still ammonia in the tank. I didnt have much salt left so I took out 5 gallons and put back five gallons with enough salt. If youve read this far I have a couple questions- How often do i check for ammonia and all of that, will my fish b ok, and plz email me and help me with my tank. I NEED A MENTOR
