Is my cycle broken?

I have now had the tank for a week and still no spike or even a slight increase in nitrate. I mixed the saltwater myself and added in around four pounds of live rock and a few pounds of live sand. There was quite a few hitchhikers who have kept the tank clean but is it possible to skip the cycle because of the LR and LS maybe? Also I thought I would mention that the tank is relatively small like 5 gallons any information would help im just curious what is going on with the tank all parameters are stable.

You can have what I will call a clean cycle. You start off with little waste in the system and grow out a small bio-filter. This is ok if you make small additions to the tank over several weeks. This will let the bio-filter grow out with each addition and maintain low levels of nitrate. If you were to add a number of fish that needed to be feed that may give you a raise in nitrate that the bio-filter cant keep up with.

alright so If I add a fish just watch the levels and make sure it doesnt spike? one fish shouldnt have to much output. As of right now there is a small clean up crew and shrimp. I have added some food to feed the shrimp so I would immagine that would cause some nitrate

its only been a week. what did you add to start the cycle? what are your ammonia and nitrite readings? they will show up before nitrates will.

Put a peice of cocktail shrimp in there to kickstart your cycle. I don't think it's even started yet, IMO
How big is your tank?

well that is sort of my question would it take longer than a week to start I added some LR and LS the LR had quit a bit of dead alge and other stuff hanging off it. Also I have added some other fish food to feel the small shrimp that came in the tank. I over fed him the last two times so there is a bit of food floating around would that start it or no?

If you are testing and reading the test right and not getting any nitrate you are ok. You put some waste in the system by feeding and the bio-filter is handling it for now. Keep an eye on it and don’t stock it to fast and you will be fine. It is only 5 gals so you could do lots of water changes to keep it in line if you did get a spike.
