In my 56 gal tank I only have 30 lbs of live rock. Everything been running great with no detectable ammonia and nitrite. I have 4 fish, 2 cleaner shrimp, and multiple snails and crabs. I plan on buying 20-25 pounds more of live rock tonight from a guy who has it in one of his tanks and transporting the rock in a bucket with heated water. Will this rock cause an ammonia spike or can I just add it all and not worry about it. I would consider it cured rock since its coming from his established tank. My thought is there should be basically no die off in the transfer process. Am I correct in my assumption?
 
The first tank we bought it from had a few round shaped fish in it (they weren't tangs, I'm not sure what it was actually) and lots of live rock. I think there were 3 fish in it, I couldn't tell as they were scared to death of us trying to get rock out. I know some of the other tanks just had a lot of live rock in them, and that seemed to be it..
I guess we shall see when we go tonight.
 
We bought 25 pounds of live rock and added it to the tank last night. I checked the ammonia this morning and its 0.25. How harmful is this short term? I'm in the process of making more r/o water to do a 40-50% water change tonight. I'm hoping the ammonia will start going back down and not back up.

I have ammolock and amquel+. I have been debating on adding one or the other. I just hate adding chemicals to the tank that aren't needed. Any suggestions?
 
Thanks! I'll check the ammonia again and see what its doing, add amquill, and do a water change tonight. I probably should have cured the rock again, but it came from an established tank so I thought it would be okay.

I swear by Amquel + so much so I ordered some earlier today. I've used it in the past to help get levels down but I do try other ways so that I'm not always relying on it.
 
I've heard that Amquel and other products that detoxify ammonia will give false ammonia readings. How long does this occur? Or do certain test kits show the correct ammonia amount, and even though it shows ammonia its detoxified? Or do they just show the toxic ammonia amount? I have both the instant ocean test kit and the mardel ammonia strip test.
