How long does liverock stay alive for

[Avidanthias]

I’ve left a tank without and filters or light on for a week now in my garage. I live in Florida so it’s pretty hot and the tank didn’t have any aeration. How long would the live rock and live sand live in the tank without dying

I've seen it stay alive for a year as long as it doesn't freeze.

Okay sweet, so you thinks it’s safe to put back in my display tank without causing any problems or a raise in nitrates

I don't know about that. I would expect a mini cycle.

These are just my thoughts and not a professional opinion; I'd be more concerned about ammonia from any possible die off, maybe test the water it's in right now. If there's any measurable amount then put the rock and water in a temperature controlled container and add a bottle of bacteria like biospira before adding it back to your dt

Live rock and live sand is rock and sand that has stuff living in and on it. Based on the situation that you described then some of that stuff probably died and some of that stuff is probably still living. Part of the way forward (in addition to the good advice above) will also depend on what else is in the tank that you are putting it in, how much rock, how big is the tank, etc. If you have a small tank with sensitive corals and a lot of rock then that would be different than a well established fish only tank with a few pieces of rock. Either way, I would suggest that you proceed with caution on behalf of the fish and livestock in your tank. Testing the water as you cycle the rock in a separate container would seem to be a good risk management approach. Because there is some living stuff still on the rock then you may not need to add any additional additives (not that it would hurt). Good luck!

Here's what I'm doing. I got some garage rock. I brought it in and tried to match the temp with my tank. I also added a small amount of my tank water and biospira. I was concerned about ammonia from any die off that was already mentioned.
